# Addition and Subtraction (Easy)

**Subtraction is taking away a number** from another number. Addition and subtraction are important skills: you've got to be able to check that you've been given the right change, haven't you? This quiz will give you a bit of practice in adding and subtracting. TIP: With numbers less than 100, add the tens first and then add the units. For example: 12 + 37 + 47 = (10 + 30 + 40) + (2 + 7 + 7) = 80 + 16 = 96.

Try to do this stuff in your head.
