Mathematics

What? 

I have been learning to solve addition problems by first jumping by a tidy number then jumping back

I have been learning to solve addition problems by using compensating from tidy numbers

So What?

I have learned that when you have an equation like 73 - 28  = you can either add the same number to both sides, or you can subtract the same number from both sides. 

Now What?

My next step is to use this strategy independently
