TermDefinition
Integer The whole numbers and their opposites.
Signed Number Positive and negative numbers.

Commutative Property of Addition Numbers can be added in any order and the sum will remain the same. a + b = b + a
Associative Property of Addition Changing the grouping in which numbers are added, doesn't affect the result of the sum. (a + b) + c = c + (b + a)
Additive Property Any number added to 0 remains unchanged. a + 0 = a
Commutative Property of Multiplication Numbers can be multiplied in any order and the product will remain the same. a(b) = b(a)
Associative Property of Multiplication Changing the grouping in which numbers are multiplied, doesn't affect the result of the product. (a * b) * c = c * (b * a)
Distributive Property The property that states that multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. a x (b + c) = (a x b) + (a x c)
Multiplicative Identity Property You can multiply 1 to any number and it keeps its identity. The product remains the same. a * 1 = a
Zero Property of Multiplication The product of any number with zero is 0. a * 0 = 0
