Question

13×7 =28 prove it now I know then how many people know many tricks.​

Answer 1

13 × 7= 28 this is not true

the true answer is 13×7=91

Answer 2

Answer:

We know that anything multiplied by a number is equals to the addition of the number the same times.

Ex- 2 × 3 = 2 + 2 + 2 = 6

Here, 2 is added 3 times.

Therefore,

When 13 is multiplied by 7 it means that the result must be 13 added 7 times.

i.e, 13 + 13 +13 +13 +13 + 13 +13 which eQuals to 91.

therefore, it can't be proved that 13*7 = 28 because it is equal to 91.

Hope you got it!!☺☺
