My week 6 problem solving

Walt: add and subtract decimals.

We have been learning to add decimals also subtract decimals. The other thing we learnt when we are adding decimals, is that we can add subtract. That is rounding up to the close number like: 15.12+17.15=,
so you go like this: 12+88=1.0 then, 15+1.0=16.0+1.15=17.15.
So add the ones you added to round. So 88+1.15=2.3.
