That is freaking amazing. Thanks
I see now, the 34 messed me up on the logic
Love these
34 x 36 = 924 + 120 + 180 = 924 + 300 = 1224 ✓
34 x 36 = 68 x 18 = 136 x 9 = 1224 ✓
34 x 36 =. X. 3. 4
3. 9. 12
6. 18. 24.
9 / 30 / 24. = 1224 ✓
34 x 36 = ( 30 + 4 ) x 36 = 1080 + 144 = 1224 ✓
34 x 36 = 34 x ( 30 + 6 ) = 1020 + 204 = 1224 ✓
34 x 36 = 34 x (40 - 4) = 1360 - 136 = 1224 ✓
34 x 36 = (40 - 6) x 36 = 1440 - 216 = 1224 ✓
34 x 36 = (40 - 6) x (40 - 4) = 1600 - 160 - 240 + 24 = 1624 - 400 = 1224 ✓
Why can’t I get the correct answer using this method to 68x69? Calculator says 4692 where as I get 4272
This is not applying on 39×34 and 39×34
Pls ans
Yup. It only fits certain numbers, even those with matching digits in the tens column.
I dont get the logic on the 53 X 57
Yes, how can it be 30?
6x5=30
This is a nice trick 🙂
But I dont get the second example.
Using the logic from the first example it should be:
5x5=25
3x7=21
So using this logic the result *should* be 2521 instead of 3021, which is correct. I just dont get why it's not 2521.
Can someone explain where he gets the 5x6=30 from?? 😮
I dont see a 6 anywhere.
@@FunkymarcherYou multiply "the tenth of the first number + 1" with "the tenth of the second number", that's where the 6 came from (5+1)
Then you multiply the units number with the other units number
34 --- 3+1 = 4
36 --- 3
4*3 = 12
Then units part
53 --- 5+1 = 6
57 --- 5
6*5 = 30
Then units part
The first example with 34 is confusing because it makes you think the 4*3 comes from multiplying the digits of the first number together
It 's still not working I did the same for 89×97.
9+1=10
10×7=70
9×8=72
So it is 7072
But the real Number is 8633
Can we hace this with random numbers
