Question

Estimate and then find product 4*979

Answer 1

First you estimate by doing 980 multiplied by 4 which is 3,920.
Then you do the final product which is 979 multiplied by 4 3,916

Answer 2

3916

Explanation:

Given expression,

`4* 979`

Since, direct multiplication is calculative,

Thus, we must split 979 in tens or hundred to ease the calculation,

∵ 979 = 900 + 70 + 9

⇒ 4 × 979 = 4 × ( 900 + 70 + 9 )

= 4 × 900 + 4 × 70 + 4 × 9

= 3600 + 280 + 36

= 3916

Hence, the product of 4 and 979 is 3916
