Addition of Integers
Key Questions

Integers are positive and negative whole numbers (3, 2, 1, 0, 1, 2, 3...).
They can be thought of as "nice numbers" as they are real and are not fractions or decimals.

Associative Property of Addition
#(a+b)+c=a+(b+c)#
I hope that this was helpful.

The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.
Examples:

2 + 4 = 6 and 4 + 2 = 6

3 + 1 + 8 = 12, and 8 + 1 + 3 = 12, and 1 + 8 + 3 = 12, etc.
