In maths we have being learning to add and subtract money. In this presentation I go shopping and buy things. I add up the total of the money to see how much it cost, and then I subtract to see how much change I get back.
In slide 2, I got how much money I had, then in brackets I added up the total of the cost. The cost of all the items were $6.60, so I got back $13.40.
