I'm stunned. Shocked. Utterly floored. Never heard of this before. When I was in school, the ONLY accepted system was to somehow memorize the entire times tables of 100 abstract numbers, which always had certain numbers (like the 7s and 8s) that were orders of magnitude more difficult to remember than any others... and the system totally broke when going above 11x11. Even if you had the times table tattooed on the back of your hand, you were helpless without a calculator if you were working outside the table. Worst of all, as soon as you graduate, you no longer use any of it and rapidly forget everything above multiplying by 2. But seeing this... I have to ask: HOW does it work? What is the logic behind this system? Also, what if there's a zero in the numbers? I'm obviously not asking about multiplying by zero; I mean a number like 10, 20, 100, etc.

@DaveHax10 жыл бұрын
I agree that if you were to use this method in a lesson for students, understanding how and why it works would be a valuable exercise. Out of the classroom though, and in the day to day world, most of the time people do not need to understand why multiplying one number by another gives a certain answer, they just need the correct answer. This method will help them achieve that (could be useful if they haven't got a calculator to hand) and whether they understand how or why it works is largely irreverent, the technique is still effective and can serve real value.
@DarthAlphaTheGreat10 жыл бұрын
DaveHax This method is too slow for 3 digits or higher. If you want practical and fast, "memorize" (in class, teachers should provide tricks and tips to do so) the multiplication table, and break them down to 10s (350 = 3 x10^2 +5*10 + 0). For really large numbers, this method really involves a lot of grouping and counting points etc. This method is mainly good as an example to ask student "explain why this works". It is only an "ok" method for day-to-day application (w/o calculator)/estimation in comparison to scientific notation etc.

To multiply with 0 on it, go 0:38 and pretend it is 13 x 20 instead of 13 x 21. The where the 0 met means that there is no line, thus leaving it like an open 2d box. You count the dots IF ONLY THERE IS LINES THAT ARE INTERSECT. For example, 11 x 0. That should leave a parallel line with gap on the middle. Hence no lines have been intersect, the answer will be 0.

Yes. Anyone who has done math in their head for a bit should know this, but it can be really fast. It not being fast is inexperience. All this method does is break up two digit multiplication into multiplying the tens, then the tens and the ones, and then the ones, and then adding them back up. It's okay, but you might as well skip the drawing if you're going to bother.

Interesting trick and a very good visual explanation. After trying it I found out that counting dots is much slower then using a multiplication table. Try to do 6x8 or 98x76 and you'll see it yourself. For zeros inside numbers I used dotted lines - it worked (any intersection with a dotted line equals 0). But if to draw just 1 line for each digit with a number on its ends and at the intersections, then the picture is simplified and you just multiplying numbers at the intersections and then adding them as was shown. This way the speed is almost the same as doing it traditionally.

So basically the same thing only the order in which you count is diffrent. But I haven't checked it for 400*58 or similar so i dont know about those.

This is equivalent to the standard method we learn at primary school. To see why, use larger digits like 89 x 78 and notice that, instead of counting intersections, you'll be multiplying digits, carrying and adding the carry to the next column - just like you do in the standard method. The difference is the standard method is quicker. It is quicker to write the digit '9' than it is to draw nine lines.

Do a dotted line
@jasleennahal73298 жыл бұрын
Naveed Akbar Yes. Draw a dotted line and write a zero in that column. If it's in the middle column, then don't add anything to the previous number.

DO NOT DRAW 10 LINES!!! That is incorrect

For me, myself, I think this trick is more complicated than the original trick. But still, fun to watch.

To me I do it like this: 99 X 87 is like [90*80 +(90*7) ]+ [9*80 + 9*7] = 8613 90*80 90*7 9*80 9*7 and then add them all = Answer Always make it with tenth multiplication number because it will be the same normal multiply of 1 to 10 with you adding Zero to the end. So a 90*80 should be like 9*8=72 and add the Two Zeros which makes it 7200. Cut the 99 into 90 and 9 and multiply it with 87 which you do the same to it 80 alone and 7 alone. Should give you an easy time, at least to me. So 99*99 [(90*90)+(90*9)]+(9*90)+(9*9)] = 9801 401*21 = 400*20 + 400*1 + 0*20 + 0*1+ 1*20 + 1*1 = 8000 + 400 + 0+ 0+ 20+ 1 =8421 Complicated? To me not XD
