To determine how much pizza is left, we can subtract the number of pieces Tom ate from the total number of pieces he had initially.

Tom initially had 8 pieces of pizza, and he ate 1.

To find out how much is left, subtract the number of pieces he ate from the initial total:

8 - 1 = 7

Therefore, there are 7 pieces of pizza left.
