Question

use the distributive property to of multiplication over addition subtraction to evaluate the following 345 multiply 1008
​

Answer 1

It can be written as

= 258 × (1000 + 8)

By using distributivity of multiplication over addition of whole numbers

= (258 × 1000) + (258 × 8)

On further calculation

= 258000 + 2064

We get

= 260064

Answer 2

first you must know the distributive property {

$a \times (b + c) =( a \times b) + (b \times c)$

so

$345 \times 1008 = 345 \times (1000 + 8) \\ = 345 000 + 2760 \\ = 347760$
