Addition

Adding a 2-digit and a 1-digit number

Example 1. Add 35 and 3.

Solution. We can use a number strip to find the answer.

31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

Find 35 on the number strip. Move forward 3 places, you reach 38.

Thus, 35 + 3 = 38.
We can also use vertical addition to find the answer.

Step 1. Add the ones. Step 2. Add the tens.

T O T O

3 5 3 5

+ 3 + 3

8 + 3 8

Thus, 35 + 3 = 38.
