Maths strategy

Strategy Equalisation:

In Room 15, we are learning what we know already about maths and what were supposed to know about maths depending on our stage. So we have to learn our strategies. One of the strategies is the equalisation strategy.

In this strategy, you have to round your numbers to a base number which is comfortable with you so you can add or minus your equation. For example, Instead of doing 403 - 97, you can do 406-97=50
Try doing 63 + 76 using this strategy and post it in the comments.
