I bought 10 oranges and ate 3 oranges out of the 10 oranges. How many oranges do I have left?

just subtract 3 from 10.

To determine how many oranges you have left, you can subtract the number of oranges you ate from the total number of oranges you initially bought.

In this case, you bought 10 oranges and ate 3. So, the calculation would be:

10 - 3 = 7

Therefore, you have 7 oranges left.
