Answer: 4. Identity Property of Addition.
Step-by-step explanation: Commutative property of addition: Changing the order of addends does not change the sum. For example, 4 + 2 = 2 + 4.
Associative property of addition: Changing the grouping of addends does not change the sum. For example, (2 + 3) + 4 = 2 + (3 + 4).
Identity property of addition: The sum of 0 and any number is that number. For example, 0 + 4 = 4.
Zero Property of Multiplication: Multiplying any number by zero, which results in the answer or product always being 0. For example, 0 x 6 = 0.
It also wouldn't be Zero Property of Multiplication because we're not multiplying, we're adding. But the answer is actually option 4, Identity Property of Addition. I hope this helps.
