amy had 80 apples and she gave 20 to lilly and gave 11 to emme so how many apples are there

The first four words of your statement already explicate how many apples there are.

If you want to find how many are left, then subtract the amounts given away.

To determine the number of apples remaining after Amy gave some to Lilly and Emme, you can subtract the total number of apples she gave away from the initial number of apples she had.

- Start with the initial number of apples Amy had: 80 apples.
- Subtract the number of apples she gave to Lilly: 20 apples.
- Subtract the number of apples she gave to Emme: 11 apples.

Thus, the calculation would be: 80 apples - 20 apples - 11 apples.

By performing the calculation, we find that there are 49 apples remaining after Amy gave some to Lilly and Emme.
