Question

Your friend says that when multiplying 400 by 132, he can multiply 4 x 132 and write three zeros after the product. Is your friend correct? Explain.

Answer 1

It should be two zeros, not three zeros.

This is because there are two zeros in the number 400.

400 x 132 = 52800 because 4 x 132 = 528, then we stick on the two zeros at the end as mentioned.
