__Adding and Subtracting are Related__

__Adding and Subtracting are Related__### Adding means to increase your original size (making it bigger). You are adding more to the original.

### If I started with 2 apples and I add 3 more apples to the original, now I have 5 apples.

__Subtraction__

__Subtraction__### Subtracting means to decrease (take away) from your original amount. You are making the original amount smaller.

### If I started with 5 apples and I take away 2 apples from the original, now I have 3 apples left.
