In this worksheet, students practise their subtraction. Key stage:  KS 2

Curriculum topic:   Number: Addition and Subtraction

Curriculum subtopic:   Solve Add/Subtract Problems to 1000

Difficulty level:   ### QUESTION 1 of 10

In this worksheet you have to answer mixed questions all about subtraction.

Subtracting is all about taking numbers away.

Example 1

Work out:

21 - 7

You should know that 11 - 7 = 4, so

21 - 7  = 14

Example 2

What is the missing number?

___ - 12 = 29

Here we use the opposite of subtraction, which is addition, to work out the starting number of the given subtraction.

We must work out 12 + 29

Add the units 2 + 9 = 11

Add the tens 10 + 20 = 30

Add the two results 11 + 30 = 41

12 + 29 = 41

41 - 12 = 29

Example 3

Work out:

43 - 29

Here we subtract 30 instead of 29.

Then we add 1 back at the end.

This is because we subtracted 1 too many by subtracting 30 instead of 29.

43 - 30 = 13

13 + 1 = 14

43 - 29  = 14
