Repeated addition by 13’s means the multiplication table of 13.

(i) When 7 heaps of 13 footballs each.

By repeated addition we can show 13 + 13 + 13 + 13 + 13 + 13 + 13 = 91

Then, thirteen 7 times or 7 thirteen’s

7 × 13 = 91

Therefore, there are 91 footballs.

(ii) When 12 rows of 13 soldiers each.

By repeated addition we can show 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 + 13 = 156

Then, thirteen 12 times or 12 thirteen’s
