In this activity, we will be answering some simple subtraction questions.
Example
Fill in the missing number.
| 35 | − | 4 | = |
You can use the number line to help you count.
35 - 4 = 31
Tips
Remember, when the second number in the number sentence is missing, we can subtract the number after the equals sign to find the missing number.
| 9 | − | = | 3 |
To solve this we would do 9 - 3 = 6
When it is the first number missing, we add together the other two numbers to find the missing number.
| − | 5 | = | 9 |
To solve this we would do 5 + 9 = 14
Are you happy with that?
Let's get started.
