What is the property

a+ (6 + 12) = (b + 12) + a

Communicative property of addition

Step-by-step explanation:

a+ (6+ 12) = (6+ 12) + a

For any two real numbers, like a and b,

a + b =  b + a

which represents the communicative property of addition. In the given problem, a represents a, whereas b represents (6+12). As per the above property, the equation can be written as, a+ (6+ 12) = (6+ 12) + a, and changing the order of addition doesn't change the answer which shows the communicative property of addition.
