Question

Two ways to find the product of 8 times 997 using mental math!!! I need help.

Answer 1

8times997 and 997times8 boom

Answer 2

Explanation:

997+997+997+997+997+997+997+997=?

or

997

x 8=???

first 7 x 8=56

997

x 8=??6

9 x 8=? than + 5(the five is from the 56 since the 7 is in the ones place the 5 goes to the tens)

9 x 8=72+5=77

997

x 8=?76

9 x 8 = ? than add 7 this time

72+7=79

997

x 8=7,976

since there is no number in the thousands the 70 79 just goes into the thousands but as itself
