Multiplication Table of 21

Repeated addition by 21’s means the multiplication table of 21.

(i) When 6 rows of twenty-one soldiers each.

By repeated addition we can show 21 + 21 + 21 + 21 + 21 + 21 = 126

Then, twenty-one 6 times or 6 twenty-one’s

6 × 21 = 126

Therefore, there are 126 soldiers.

(ii) When 9 bunches each having 21 flowers.

By repeated addition we can show 21 + 21 + 21 + 21 + 21 + 21 + 21 + 21 + 21 = 189

Then, twenty-one 9 times or 9 twenty-one’s

9 × 21 = 189

Therefore, there are 189 flowers.

We will learn how to use the number line for counting the multiplication table of 21.

(i) Start at 0. Hop 21, four times. Stop at 84.

4 twenty-one’s are 84 4 × 21 = 84

(ii) Start at 0. Hop 21, seven times.

Stop at ____. Thus, it will be 147

7 twenty-one’s are 147 7 × 21 = 147

(iii) Start at 0. Hop 21, eleven times.

Stop at ____. Thus, it will be 231

11 twenty-one’s are 231 11 × 21 = 231
