If a pizza is cut into 8 equal slices and you eat 3, how many slices are left?

To determine how many slices are left after eating 3 out of the 8 equal slices of pizza, you start with the total number of slices, which is 8. When you consume 3 slices, you must subtract that number from the total:

8 slices - 3 slices = 5 slices.

Thus, the remaining number of slices after eating 3 is 5. This calculation highlights the importance of performing basic arithmetic accurately, as it allows you to see the direct relationship between the total quantity and how much has been taken away. The other options do not reflect this straightforward subtraction, leading to incorrect conclusions about the number of slices left.
