Question

Which property is illustrated by this problem? 99.78 + 0 = 99.78

Answer 1

Identity property of addition.

Explanation:

The identity property of addition says that the sum of 0 and any number is that number. So 99.78 + 0 = 99.78 is identity property of addition. This is true because the definition of 0 is "no quantity", so when we add 0, the number doesn't change.
