Question

Multiply 53 by 24, firstly by breaking down 24 in its terms (20 + 4) and secondly by breaking down 24 in its factors (6 * 8). Show all your steps.

Answer 1

$$53\times24=53\times(20+4)=53\times20+53\times4$$

$$=1060+212=1272$$

$$53\times24=53\times(3\times8)=(53\times3)\times8$$

$$=159\times8=1272$$
