Choice B) Commutative Property is the answer

The commutative property of addition says that we can add two numbers in any order. For example: 2+3 = 5 and 3+2 = 5.

In general, the rule can be written as x+y = y+x. The x and y are simply placeholders for numbers. You can think of them as empty boxes to write a number inside. In this case, we have 7.2 for one of the boxes and -5.5 as the other value in the other box.
