ALEKS

Commutative Property of Multiplication

States that two numbers can be multiplied in either order. example: 40 x 10 = 10 x 40 a x b = b x a

RULES :When Multiplying & Dividing Integers

Positive X Positive = Positive Positive X Negative = Negative Negative X Positive = Negative Negative X Negative = Positive

Additive Property of Zero

States that when you have any number and add zero to it, your answer will always equal the original number. ... Let x be any number. Zero plus x will always be equal to x.

Zero Property of Multiplication

That when we multiple a number times zero the product is zero. example 7 x 0 = 0 a x 0 = 0

Associative Property of Addition

The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis. example: 1 + (2+ 4)= (1+ 2)+ 4 a+ (b+ c)= (a+ b)+ c

Identity Property of Addition

The identity property of addition simply states that when you add zero to any number, it equals the number itself. example: 5 + 0 = 5 a + 0 = 0

Commutative Property of Addition

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2.

Identity Property of Multiplication

When we multiply a number times 1 the product is equal to the original number. example: 8 x 1 = 8 a x 1 = a

Associative Property of Multiplication

When you multiple more than 2 numbers the grouping of the factors does not change the product. example: 2 x (3x 4) = (2 x 3 ) x 4 a x (b x c) = (a x b) x c
