Multiplication Table of 20

Repeated addition by 20’s means the multiplication table of 20.

(i) When 5 candle-stands having 20 candles each.

By repeated addition we can show 20 + 20 + 20 + 20 + 20 = 100

Then, twenty 5 times or 5 twenty’s

5 × 20 = 100

Therefore, there are 100 candles.

(ii) When 8 bundles of 20 pencils each.

By repeated addition we can show 20 + 20 + 20 + 20 + 20 + 20 + 20 + 20= 160

Then, twenty 8 times or 8 twenty’s

8 × 20 = 160

Therefore, there are 160 pencils.

We will learn how to use the number line for counting the multiplication table of 20.

$20 Times Table on Number Line$

(i) Start at 0. Hop 20, three times. Stop at 60.

3 twenty’s are 60 3 × 20 = 60

(ii) Start at 0. Hop 20, ten times.

Stop at ____. Thus, it will be 200

10 twenty’s are 200 10 × 20 = 200

(iii) Start at 0. Hop 20, twelve times.

Stop at ____. Thus, it will be 240

12 twenty’s are 240 12 × 20 = 240
