Answer:

Step-by-step 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
