Math in… Eating Apples

What is the mathematical relationship between your bite of apple and the remaining part?

In mathematics, when you have a smaller part that’s a part of a larger whole, the complement of that smaller part in the larger whole is simply what’s left when you’ve taken the smaller part away. When you take a bite from an apple, the complement to that bite is the rest of the apple that remains!

Shapes offer a clear way to understand complements. Imagine cutting a smaller circle from a larger one. What shape is left as its complement?
