Warm up question, Jonny has 6 apples and Aiden asked if he can get 2 apples, and Jonny gave him 2 apples. How many apples does Jonny have left? Explain how you got the answer.

He has 6, he loses 2.

6 (first amount) - 2 (amount given away) = 4 (amount retained)

We can check this by adding the answer to the amount taken away. If it makes 6, we are correct.
