WALT: Add and Subtract Decimals.

Today me and my friend Revival did this presentation to show our understanding of decimals. I learnt how to subtract and add decimal it is really easy to some of us. Here is an example: 0.4 + 0.5= so first I did 4 + 5= 9 and then I do 0 + 0= 0 so we just need to add a decimal point and there is our answer 0.9.
