Final answer:
The number sentence '52 + 0 = 52' is showing the Additive Identity Property. According to this property, when zero is added to any number, the number remains the same.
Step-by-step explanation:
The number sentence '52 + 0 = 52' is demonstrating the Additive Identity Property of numbers. In mathematics, the Additive Identity Property states that any number plus zero will result in the original number itself. In this example, adding zero (0) to fifty-two (52) returns fifty-two (52), which is the original number, thus exemplifying the Additive Identity Property.
