Answer 1

Question:-

A student multipled 4065 by 36 instead of 63. By how much was his answer smaller than the

correct answer?

Answer:-

Correct Answer:-

4065 * 63

Wrong Answer:-

4065 * 36

Difference between Correct answer and wrong answer:-

(4065 * 63) - (4065 * 36)

==>4065 * (63 - 36)

==>4065 * 27

==>109755

We have not calculated (4065 * 63) and (4065 * 36) but we have applied distributive law so that we have to multiply only 1 time.
