Which of these expressions demonstrates the identity property? Check all that apply.

The identity property says that combining a number with the appropriate identity value leaves it unchanged. Multiplying by 1 keeps 25 the same, so 25(1) = 25 demonstrates the multiplication identity. Adding 0 also keeps 25 the same, so 25 + 0 = 25 demonstrates the addition identity. The other expressions do not equal 25: 25(0) = 0, and 25 + 1 = 26.
