In this worksheet, students work out combined calculations involving addition and subtraction of decimals. Key stage:  KS 3

Curriculum topic:   Number

Curriculum subtopic:   Use Four Operations for All Numbers

Difficulty level:   ### QUESTION 1 of 10

In this worksheet, we will learn how to do combined addition and subtraction of decimal numbers.

Example

Do the following additions and subtractions.

Remember to keep the decimal point and equivalent digits lined up in the correct columns.

579.6 - 23.02 + 614.7 - 11 = _________

This can be worked out in several different ways.

One way is to identify the additions and the subtractions.

579.6 - 23.02 + 614.7 - 11

Then add the blue numbers to get 579.6 + 614.7 = 1194.3

Then add the red numbers to get 23.02 + 11 = 34.02

Then subtract 1194.3 - 34.02 = 1160.28

Do the following additions and subtractions.

810.8 - 48.9 + 176.7 - 28 = _________
