Addition and subtraction

WALT: use equal addition
Description:I've been using equal addition. This is a subtraction only strategy. It's when you round one of the numbers to the nearest 10 by adding a number to it. Then you add the same amount to the number on the other side.

This is how I think I did 
I think Tui did well
