Question

11*11=4 22*22=16 33*33=?

Answer 1

Doing the multiplication and then taking the sum of the digits in the answer. In other words, this is finding the “sum of the digits in the product.”

11 × 11 = 121 → 1 + 2 + 1 = 4
22 × 22 = 484 → 4 + 8 + 4 = 16

This procedure suggests an answer of 18.

33 × 33 = 1089 → 1 + 0 + 8 + 9 = 18

The “sum of the digits of the product” gives 18.

Answer 2

The answer would be 64
