Addition on a Number Line

Addi on on a number line is coun ng forward.

Let’s take an example, 2 + 3 = ?
The fi rst number is 2. Start from 2 on the number line. The second number
is 3. To add 3, count forward 3 from 2. You will reach 5 which is the answer.
So, 2 + 3 = 5.

0 1 2 3 4 5 6 7 8 9

Let’s take another example, 5 + 3 = ?
Star ng from 5, count forward 3 to reach 8. So, 5 + 3 = 8.

0 1 2 3 4 5 6 7 8 9
