# 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.

(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

How to read and write the table of 18?

The above chart will help us to read and write the 18 times table.

 Read 1 eighteen is 18 2 eighteen’s are 36 3 eighteen’s are 54 4 eighteen’s are 72 5 eighteen’s are 90 6 eighteen’s are 108 7 eighteen’s are 126 8 eighteen’s are 144 9 eighteen’s are 162 10 eighteen’s are 180 11 eighteen’s are 198 12 eighteen’s are 216 Write 1 × 18 = 18 2 × 18 = 36 3 × 18 = 54 4 × 18 = 72 5 × 18 = 90 6 × 18 = 108 7 × 18 = 126 8 × 18 = 144 9 × 18 = 162 10 × 18 = 180 11 × 18 = 198 12 × 18 = 216

Now we will learn how to do forward counting and backward counting by 18’s.

Forward counting by 18’s: 0, 18, 36, 54, 72, 90, 108, 126, 144, 162, 180, 198, 216, 234, 252, 270, 288, 306, 324, 342, 360, 378, 396, 414, 432, 450, ……

Backward counting by 18’s: ……, 450, 432, 414, 396, 378, 360, 342, 324, 306, 288, 270, 252, 234, 216, 198, 180, 162, 144, 126, 108, 90, 72, 54, 36, 18, 0
