Multiplication Table of 15

Repeated addition by 15’s means the multiplication table of 15.

(i) When 8 rows of fifteen men each.

By repeated addition we can show 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 = 120

Then, fifteen 8 times or 8 fifteen’s

8 × 15 = 120

Therefore, there are 120 men.

(ii) When 11 flower-vase having 15 roses each.

By repeated addition we can show 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 = 165

Then, fifteen 11 times or 11 fifteen’s

11 × 15 = 165

Therefore, there are 165 roses.

We will learn how to use the number line for counting the multiplication table of 15.

(i) Start at 0. Hop 15, three times. Stop at 45.

3 fifteen’s are 45 3 × 15 = 45

(ii) Start at 0. Hop 15, five times.

Stop at ____. Thus, it will be 75

5 fifteen’s are 75 5 × 15 = 75

(iii) Start at 0. Hop 15, nine times.

Stop at ____. Thus, it will be 135

9 fifteen’s are 135 9 × 15 = 135

12 × 15 = 180

Now we will learn how to do forward counting and backward counting by 15’s.

Forward counting by 15’s: 0, 15, 30, 45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195, 210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375, ……

Backward counting by 15’s: ……, 375, 360, 345, 330, 315, 300, 285, 270, 255, 240, 225, 210, 195, 180, 165, 150, 135, 120, 105, 90, 75, 60, 45, 30, 15, 0
