[@ManojKumar-ee6fv]

MindYourDecisions hey presh I completed solving 2 of them and I haven’t seen the rest part of the video

[@ManojKumar-ee6fv]

MindYourDecisions hey i ve an other solution for the third one ... leave the 3 and 4th box as it is and cancel out the rest matches (counts:5) But your method seemed to very good . But please check out my method too

[@danielchowtzeyoong]

a) Remove 2 sticks to leave 3 squares b) Remove 4 sticks to leave 2 squares this is better?!

[@brd8764]

[@simon_patterson]

That's 3 neat solutions. I didn't see a rule that said you couldn't have sticks left dangling, so I thought 1 and 3 were simple. I enjoyed your solution to 2 though.

[@AmitSharma-wh2mw]

Simon Patterson but these rule are known in match stick puzzle. you can find match stick puzzle game on playstore

[@puschelhornchen9484]

@@AmitSharma-wh2mwis this rule really needed? A square is a square.

[@ineverchangemyplayericon3016]

Same I call bs on the rules

[@andrewstallard6927]

For part b I got the same thing as Presh but for parts a and c my solutions had dangling sticks. He should have been clearer about the specs.

[@kerwin392]

Just think of that rule as a optimization problem. In computer systems optimization is key.

[@NestorAbad]

I played these with my children and we enjoyed a lot, thanks!

This is probably overdone but I think "precious tile worker" is the funniest caption I've seen of your name to date. On par with Cumberbatch.

[@ivanljujic4128]

[@windersteria]

don't forget "pressure cooker"

[@G.Aaron.Fisher]

It would be nice if you could provide exact definitions for these puzzles, to clarify whether it's a math puzzle or a "lateral thinking" puzzle. In this case, the precise rules are "Remove N matchsticks so that 1) exactly X squares coincide with the remaining matchsticks, and 2) each remaining matchstick coincides with the perimeter of at least one of those squares." Relaxing either of those conditions permits multiple unintended solutions.

[@jensraab2902]

Exactly! You can "destroy" a square by simply removing one side. Nothing in the text indicated that this wasn't an option.

[@inigo8740]

This was incredibly easy, specially for a MYD video. Solved it while you read it. It feels nice to have gotten one for a change.

[@AbdulKarim-cw8cv]

YESSSSSSSSSSSSSSSS!!!!!!!!!!!! I FIGURED IT OUT!

[@kookeekwisp]

What happened to your famous math explanations? Come on, i had this one long before i saw this! First ask the question: How many matchsticks does it take to make a square? Using exactly four matchsticks, you start with one. To make a second square, you could use either 3 or 4 matchsticks, connecting at the corner, or using one shared side. To make a fourth, you need at least 2 more matchsticks. To determine how many squares you need to remove, you need to do some calculating. First, count the number of matchsticks, then subtract the amount of matchsticks you need to remove, which makes twelve. Divide that by the amount of squares you need, and you get, on average, how many matchsticks you need for each square. Since the result is 12, and 3 squares means we need 4 for each, which means none of the squares can be connected at the sides, or else you'd have 11 sticks with a remainder, so just look for the 3 existing squares that are connected at the corner.

[@rmsgrey]

Agreed - if the purpose of the channel is to offer insight into how to solve mathematical problems, the message of this video is that the way to solve matchstick problems of this kind is through direct inspiration, with the solution arriving fully formed in one's mind, rather than there being any way of reasoning towards a solution. There is a minor hole in your solution for the first question - the large square uses 8 matchsticks, so you need to establish that you can't add 2 squares with 4 more matchsticks in order to show that the 3 small squares solution is unique. For finding an answer, ignoring the large square and looking for 3 small squares that don't share edges is fine. For the second question, there are 6 squares total, and only 3 matches that aren't part of at least 2 squares, so only one possible solution - removing any other match would leave at most 4 squares remaining. For the third question, you're looking for 2 squares with 10 matches, so you know it has to be the large one plus two more matches to form a small one, which gives the four possible solutions - the large square with a small square in one of its four corners.

Easy clap! Got all three!

[@rohitkumar-ic5dz]

So easy man. So easy. I did all of them.

[@Minder666]

I got two squares, removing 4 sticks. :D

[@n5k681]

Same

[@sandhinfk]

same here

[@Max_Power_]

That's easier

[@fmaylinch]

I'd add this question just before the third one, because it's easier and it may leave you puzzled that by removing one match more you could also get 2 squares.

[@Packerfan130]

I got zero squares, removing all of the sticks.

[@JWentu]

nice. i figured 2 of three out

[@Scorpionwacom]

Hi, Presh! Many thanks for a simpler puzzle! Yes, I did figure this out (all three). Finally.

[@jacksainthill8974]

Had to think for a minute for the second one, but once I properly understood the question _(ding!),_ the rest was not hard. Nice puzzles, thank you.

[@StRanGerManY]

Figured each in less then 5 seconds

[@ArabianShark]

I already knew A, and managed to solve B and C, B in the same way and C leaving a different square inside the large one, but employing the same principle.

[@NukeMarine]

Pretty simple. There's others such as "Remove 2 sticks and leave 4 squares" (three possibilities) and "Remove 4 sticks and leave 2 squares".

[@georgiteodosiev9037]

These are cool, easy but cool and entertaining

[@danielbuttons5535]

For the 3rd solution you can also take our two sticks from upper left side (horizontal and vertical) and three sticks from right side ( two horizontal and one vertical) and you’ll have 2 squares

[@NachitenRemix]

I figured out that same solutions. It took me a while to realize that there are really 6 squares in the original setup not 5. Thats when it made it easy for me to solve em

[@usama57926]

thank u sir amazing puzzle

[@udaysingh5167]

This was very easy i solved it under 20seconds. Thanks for interesting maths videos.

[@brucefulton]

You can remove two sticks to leave three squares if a couple of dangling sticks are acceptable.

[@ellaenchanted2399]

For the remove 3 end with 5, if you set the matches a different way, the middle space could count as a tiny square.

[@Poet13xRatedRKO]

for c) there are more solutions (remove different 2 sticks in the middle, but this is just logical). Of course I found all of them because this video was uploadaed on my birthday!

[@paolojerichoquiniano5010]

solved everything in it in 15 seconds. easy. :)

[@SAL-9000]

Easy!

[@selvireji104]

The first one was good but the next two were inappropriate according to the figure....

[@ektameriya7328]

Thanks sir

[@fatpikachussbm1029]

A) remove the top most and leftmost horizontal stick, and the topmost second to the left vertical stick(you only need to remove 2) If you wanted it to look nicer, you could remove the topmost second to the left vertical stick and the second to the top second to the left horizontal stick. B) you can just remove The rightmost stick C) remove the four sticks that make up the cross inside the large square

[@rubixman7x7]

Dang, when my mouse hovered over the thumbnail and it played the preview, it spoiled the solution :(

[@jimmykitty]

Yeah!! I did ❤

[@xaxuser5033]

This was a good game that i saw in the past !!!

[@Crux161]

I didn’t get the same nice looking solutions. Mine always involved leftover pieces, while still meeting the requirements. But in doing that I was only able to do A and C.

[@Ecl1psed276]

I did them all in my head in like 20 seconds, these are all really easy... Also it's possible to only remove 4 sticks to have 2 squares remaining!

[@mungodude]

i got the same solutions for the first two puzzles, but for the third puzzle I removed the same three outer sticks, but a different pair of adjacent matches inside the big square.

[@sushrutdeshmukh1826]

That was my school project. Lol 😁😁😁. Ty so much

[@ostrich_dog]

You could do C removing only 4 sticks, the sticks in the middle of the large square, that would have left that big square andthe one on the top left

[@lacourgette42]

I love these type of puzzles I had a mobile game called Match dot or something like that There were around 900 puzzle like this one which is why this is my favorite type of puzzle now

[@ImaginaryMdA]

Yay, I got them! :D

[@animesloversunited9069]

my first one different but it is the answer 😅

[@thiantromp6607]

If you simply remove the middle four in the big square on the final problem, you'll also be left with 2 squares

[@padhiyarkanubha5037]

Yes

[@alan2here]

I see your solution to the first leaving only the matches that make 3 squares. As well as numerous solutions that disrupt any of the perhaps 10 possible pairs of small squares, all of witch also nicely disrupt the large square. Could make for about 21 solutions in total.

[@qwertyTRiG]

Before watching: (a) Remove 3 sticks to leave 3 squares. This is trivial unless we assume a rule against dangling sticks. To avoid dangling sticks, remove the two sticks from the bottom left corner, and the centre top, leaving three squares connected at their corners. (b) Remove 3 sticks to leave 5 squares. Remove the three sticks forming the square sticking out to the top right. This leaves four small squares which also form one large square, leaving five in total. (c) Remove 5 sticks to leave 2 squares. Remove the top right square, as in Question B. Also remove two sticks inside the larger square. This leaves one large square and one internal small square.

[@kevinerose]

There's another one called "MOVE" 2 sticks to leave 4 squares. Have you done that one yet? For the setup, typically you would start with 4 squares and ask the person to make 5 out of them by moving 2. But it is fun to do both ways. Starting with 4 squares, the setup is a farmer has 4 animal pens for cattle. Imagine the matchsticks as fences. The farmer buys more cattle and needs a fifth pen to house them but there is no money left to purchase fencing. How does the farmer move 2 fences to create 5 pens of equal size to the original 4 pens using up all the fences. No extra fences remaining or removed. edit - I just realized my puzzle looks a little different and uses 16 matchsticks instead of 15.

[@arikwolf3777]

d) Remove 2 sticks to leave 3 squares e) Change 2 sticks to make 7 squares I have done so many of these type puzzles, they are easy for me. But at one time they where not.

[@arikwolf3777]

The answer to e) is to rotate last two matchsticks that Presh removed for answer c), 180 degrees so that the four sticks make a itty-bitty square with their ends.

[@arikwolf3777]

No, e) always said change. I only miscounted the number of squares. And since e) is the only one to say change, the others say remove, it is easy to miss. I get caught misreading problems all the time.

[@kshitij1729]

Hey presh, I think that I have a funny question but I am still gonna ask. Law of gravitation is a force ((g.m1.m2)/r^2). And pressure=force/area. Putting together, we get pressure as ((g.m1.m2)/r^2.area). Does this make sense? If it does, then if distance is not=0 and the objects don't touch then how can they exert pressure on each other.

[@malmiteria]

"leave x squares" doesn't mean it has to be squares only, so u can let some random stick alone being simple segment. Does that makes sense?

[@yovo7499]

I guessed all of them

[@husanerupam5064]

Nice. Here I can make 3 squares by removing only 2 matches.

[@joec5651]

Perfect！

[@solar0wind]

I figured b and c out, but unfortunately not a.

[@harshsrivastava9570]

For once, I figured them out! Whoo!

[@TaiStar42]

a)has many solutions if you leave extra sticks b)has only the one solution c)has many solutions but how many?

[@chinareds54]

A) 2 that touch the bottom left corner plus top midde horizontal. B) 3 sticks on the right... leaves 4 small squares embedded in the big square. C) starting from b, take away any two perpendicular middle sticks to leave one small square embedded in the big square.

[@evanmurphy4850]

Thanks, I didn't quite understand the clear visual representation in the video. Glad I had your solution to help.

[@ferchavalos4681]

If I figured it out without struggling at all, I can assert to say the puzzles were kinda easy.

[@ankankisku5799]

This was pretty easy for me🤣🤣

[@sadiqdp55]

That....was wayyyy too easy

[@TheAkashicTraveller]

It's always fun when the only way to know to rules is to watch the first two solutions...

When you said question b i immeadily got the answer

[@42networks]

You can solve a in two moves if you remove two matches from inside the big square

[@primus108]

The first one is a good puzzle, however the second and third are poor.

[@letrat7021]

Remove 3 matches down the middle

[@victordelimabellia2158]

is it a problem to leave sticks not conected to the squares? For example, you could remove the three vertical sticks from the bottom, leaving three squares plus two sticks no conected with them...

[@Unigardy]

That's what I thought for a. For b and c I got the solutions he said in the video. It never said you couldn't leave extra sticks, so it's not technically wrong, but it's not the solution he was looking for

[@wynautvideos4263]

Easy af

[@sivaram9654]

i like it

[@Macieks300]

Doing the b) option also leaves 3 or 2 squares

[@Yusso]

also: remove 1 stick to leave 4 squares, remove 2 sticks to leave 4 squares, remove 2 sticks to leave 3 squares.

[@jervinsevilla6677]

It took me only a minute to solve all 3 of the matchstick puzzles.

[@WakarimasenKa]

Well.. Last time I explained how the puzzle was trivial to me, because I had seen many puzzles like it in the past. This time, I was stumped for a long time. I've solved them before. But it was a long time ago and I had lost the knack. It took me ages to solve.

[@ChoccyMilk1940]

[@peeyushchamaria]

Hey Presh Talwalkar, I have a question for you. A 40 kg iron block is cut into four pieces in such a way that all the whole number weights from 1 to 40 can be weighed using 1/2/3/4 pieces on a scale balance for any item. I have the answer for this question for a long time now but have not been able to figure out the solution for the same. Thanks

[@peeyushchamaria]

@sherlock fan on a scale balance with two pans, one on the left and one on the right, you can keep the item to be weighed on any pan and then adjust the 1 to 4 pcs of iron block on either pans. Say, for example, two of the pcs weigh 4 and 5 kya then by keeping both on the same side you'll ba able to weigh 9 kg whereas by keeping 5 kg pc on the left pan and 4 kg pc on the right pan and the material to be weighed on the right pan, you can weigh 1 kg.

[@peeyushchamaria]

@sherlock fan in the same way, you can weigh any whole number between 1-40 in one go!

[@peeyushchamaria]

@sherlock fan correct answer. But once again I have no clue about the Solution.

[@peeyushchamaria]

@sherlock fan P.S. I also wonder how is that a Computer Science problem.

[@peeyushchamaria]

@sherlock fan Thanks for the information mate!

[@3la5t1c81rdy]

Hehe I just found out that the 3rd problem is also solvable with only removing 4 matches!

[@knudplesner]

a in 2 sek; b in 3 sek; c in 60 sek, obs: a: the 3 middel sticks

[@larscandland4072]

Another solution to c). remove the 5 right most matches, which would including the 3 top right matches and the 2 matches on the right side of the big square. you'll be left with 3 matches poking out to the right, but you'll have 2 complete squares.

What are all the possibly combinations of "You can remove m sticks and leave n squares"?

[@AlqGo]

JBTechCon JBTechCon That depends on how the squares are arranged. Having said that, there is a very simple observation and, that is, you can “delete” a square (formed with exactly 4 sticks only) by removing all the sticks that are not the sides of other squares.
