Just a reminder: no matter the level of the teaching, its the perseverance that predict you results. The teacher is no wizard, they just help you on the right tack and dont think for you.

[@user-rz9iv1hx8t]

*Multiplication 5* ● when using the trachtenberg method, we start from the last digit, working our way towards the first. So from right to left ● the digit underneath will be half the number to the right ➡️ EG : 026 × 5 130 1) underneath 6 there is 0 since there are no numbers after 6. 2) underneath 2 there is 3 since half of 6 = 3 - it is important to note that in front of every number, there is an zero, and underneath the zero will be half of the first digit. - In this case there is 1 underneath 0 since half of 2 = 1 ● if the original (top) number is odd, then add 5 to the value you get after halving the number to the right 《Example》 036 × 5 180 1) here, the number under under 3 is 8. This is because half of 6 is 3, and since the original (top) number is odd, we add 5 to the half, so 3+5=8. ● it is important to remember that the half of odd numbers will not end in .5, instead we will ignore it and just use the first digit. In this case, underneath 0 is 1, since half of 3 is actually 1.5 and we have ignored the .5 *Multiplication 6* ● underneath each number, will be the original (top) value + add half of the number to its right 《Example》 026 × 6 156 - underneath the 6, there will be a 6 and nothing else since there is no other value next to the top 6 - underneath 2, there is a 5 since we halfed 6 which = 3 and added it to the original top number which is 3+2=5 - underneath 0 there is a 1 since half of 2 = 1 and 1+0=1 ● if the top digit is an odd number, then we'll do the same exact thing, however we will add an additional 5 to it. 《Example》 036 × 6 2•16 1) underneath 6 there is a 6 since there is no neighbouring digit 2) underneath 3 there is •1, this is because half of 6 is 3 so 3+3=6 then we add the additional 5 which is 6+5=11 since 11 is a two digit number, we will use the unit number and next to it we'll put a dot to represent the extra tens. 3) underneath 0 there is a 2 since half of 3 is 1 and we added the extra ten from the last digit, so 1+1=2 *Multiplication 7* ● underneath the top number, we will double the top value, then add half of the neighbouring number 《Example》 026 × 7 18•2 - underneath 6 there is a •2 which basically represents 12. This is because we double 6 which = 12 and added 0 since there is nothing next to it. - underneath 2 there is an 8, since 2×2=4 and half of 6 = 3 so 4+3=7. Then we added the extra 10 on which is 7+1=8 - underneath 0 is 1 since 0×2=0 and half of 2=1 ● just like before, if the top digit is an odd number, we will do the same thing but add an additional 5 《Example》 036 × 7 2•5•2 1) underneath 6 there is •2 since 2×6=12 2) underneath 3 there is •5, since 3×2=6 add half of 6 which is 3, so 6+3=9 Then we add the additional 5 which is 9+5=14 and then add the extra ten 14+1=15 3) underneath 0 there is a 2, since half of 3 is 1 add the extra 10 1+1=2 *Multiplication 11* ● underneath the digit, add the neighbouring number to the top value 《Example》 026 × 11 286 1) underneath 6 is 6, since there's nothing next to 6 2) underneath 2 is 8 since 6 is the neighbouring digit so 2+6=8 3) underneath 0 is 2 since 2 is the neighbouring digit

[@poproll2709]

Thanks urs is much simpler to understand 😂

[@kumarsiva5701]

Tell me how to do 598 X 5. I tried but answer not coming. pls explain it...

[@user-rz9iv1hx8t]

@kumarsiva5701 598 × 5 = 2990 0598 × 5 2990 ● the number underneath 8 is 0 since it is the last digit of the number ● the number underneath 9 is 9 because half of 8 is 4, and since 9 is an odd number, we must add 5 to 4 = 9 ● the number underneath 5 is 9 since half of 9 is 4.5 However, we must ignore the .5 And since 5 is an odd number, we must add 5 to 4 = 9 ● lastly the number underneath 0 is 2 since half of 5 is 2.5 and we will ignore the .5

Really helpful, make more videos thank you.

[@Milkman4279]

He says the keys are universal. There aren't special rules for each specific number, then shows us a bunch of special rules for each specific number 🤔

[@mathOgenius]

Great question! in a previous video in one eg multiply 54x56 very fast but with a condition that starting numbers are same and ending digits add to 10. but for this method there are no conditions like that. if you remember a key for specific number then you can multiply any number with that. its like a table for that number.

sure ! this method is also very useful for competitive exams!

Video for balance number bro

[@x.i.o.i.x]

Can we count it from the front ? If i count number with mind and count it from behind sometimes it confusing to rearrange the number

[@Nameless_Monster729]

Explanation is great. But i didn't understand one thing. How could the Trachtenberg method work in muliplication of 5, with 793 × 5? As per the rule, the neighbour of 3 is zero. But how did 5 appear in the ones place? Can you please explain? 👍

[@jatin_and_vivaan]

can you make a video on easy squares till 100

[@rajaananthi9234]

Can you pls share us a study routine 😊

This is so cool!

[@manishkarsh6836]

Sir before moving forward I would like to say that 1 is also odd number but why you didn't add 5 where as you add 5 with 3 . Explain it to me make me out of doubt sir 🤔🙏😊.

5:28 half of '3' is '1', 1 is an odd Number, why don't you add 5 ?

[@bananik6570]

Because 4 isn't odd,not one

[@FlantBG]

I’ve been knowing this 😭 I thought it was something different

[@AndrewCastellanoReal]

Thank you, does a pattern develop? I was surprised there were methods for 11 and 12 rather than extending the methods for 1-9 to 2-digit numbers.

[@bananik6570]

9:15 is it +5 because 1 is odd or (1 x 2)+1=3, 3 is odd?????

[@weewee-hy5kj]

wonderful

[@shubhajitchakraborty]

8379 * 5 = 41895. I,m stuck at 8. Please let me know how can I get 41 to complete the calc? 793 * 5 = 3965, again the same problem... You are highly appreciated for the efforts you put in to educate us. 🙏❤🧡❤🙏

[@-VND-]

1/2 of 3 =1 (8 - even -> no additional 5) and 1/2 of 8 = 4 (0 - also even so no additional 5), the same for the second number

[@dumenkosinibalufu9157]

smart pants

[@hridhaanarora6148]

@9:36 8 is even, then why add 5?

[@NickNutty]

Because the starting number that is 3 is uneven Because number means the start in here, dude I am 12 step up your game
