Answer 1

9 * 72 = 9 * (70 + 2) = 9 * 70 + 9 * 2 = ?

Answer 2

uhhh..

Answer 3

The "star" symbol I have used is same as the period symbol they have used.
They both mean multiplication.
9 x 72 = 9 x (70 + 2) = 9 x 70 + 9 x 2

So the answer in the first box should be 70.
The answer in the last box should be the result of multiply 9 and 70 added to 9 x 2.

Answer 4

9 x 70 = 630
9 x 2 = 18
630 + 18 = 648.

The answer in the first box is 70.
The answer in the second box is 648.
