Addition and Subtraction - Remember the value of each of the diene blocks! What number is shown here?

Chilli Challenges! Week 6

Add or subtract multiples of 100 (within 1000)

Remember - you can use inverse to check your calculations!

In Maths, the inverse means the opposite function. For example, addition is the inverse of subtraction and multiplication is the inverse of division. For example: 

3 + 7 = 10        10 - 7 = 3

2 x 6 = 12        12 ÷ 6 = 2


So for this week where we are focusing on adding and subtracting multiples of 100, you can use your inverse skills to check back on your answers and make sure they are correct! For example: 


200 + 300 = 500


I can use the inverse:


500 - 300 = 200


Have a go!
