Week 5 Maths

I have been learning about Equal Edition. Equal Edition is a strategy that you can use when using subtraction and one of the numbers has to be close to a hundred.  

All you have to do is add the number that equals to a hundred to both numbers. Once you have done that, the problem should be really easy to solve. Now my whole Maths Group is really good at solving those sort of maths problems.
