2. Adding Decimals To make adding decimals easy, we must keep our work organized and neat! There are 3 easy steps!

3. Adding Decimals 1.Write down the numbers, one under the other, with the decimal points lined up 2.Add zeros so the numbers have the same length 3.Then add using column addition, remembering to put the decimal point in the answer!

4. Examples 1.452 + 1.3

5. Examples 3.25 + 0.075 + 5

6. Examples 2.372 + 14.04

7. Examples 20.15 + 0.083 + 6.9

8. Examples 3.032 + 7.89 + 103.2

9. Examples 902.03 + 78.3054 + 40.039 + 1.1326

10. Subtracting Decimals We will follow the same steps as adding decimals. Let’s review those steps.
