Multiplication Table of 18

Repeated addition by 18’s means the multiplication table of 18.

(i) When 6 groups having 18 starfish each.

By repeated addition we can show 18 + 18 + 18 + 18 + 18 + 18 = 108

Then, eighteen 6 times or 6 eighteen’s

6 × 18 = 108

Therefore, there are 108 starfish.

(ii) When 8 packets of 18 chocos in each packet.

By repeated addition we can show 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 = 144

Then, eighteen 8 times or 8 eighteen’s

8 × 18 = 144

Therefore, there are 144 chocos.

We will learn how to use the number line for counting the multiplication table of 18.

$18 Times Table on Number Line$

(i) Start at 0. Hop 18, two times. Stop at 36.

2 eighteen’s are 36 2 × 18 = 36

(ii) Start at 0. Hop 18, five times.

Stop at ____. Thus, it will be 90

5 eighteen’s are 90 5 × 18 = 90

(iii) Start at 0. Hop 18, ten times.

Stop at ____. Thus, it will be 180

10 eighteen’s are 180 10 × 18 = 180
