Properties of Whole Numbers 1
Index notation
Using powers to write the repeated multiplication (eg: 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3 x 3) of a number
zero property of multiplication
a x 0 = 0 = 0 x a
identity property of multiplication
a x 1 = a = 1 x a
commutative property of multiplication
a x b = b x a
closure property of multiplication
a x b = unique whole number
Distributive Property of Multiplication Over Addition
a(b+c) = (axb) + (axc) and (a+b)c = (ac) + (bc)
Associative Property
a+(b+c) = (a+b) +c
Additive-Identity Property of Zero
a+0=0+a=a

10
last digit is even
2
add the digits up and if the sum is divisible by 3 the number is
3
last digit is 5 or 0
5
has to follow rule 2 and 3
6
take the last digit, double it, and subtract it from the rest of the number
7
last three digits as a number is divisible by 8
8
add up all the digits and divide by 9
9
Prime number
A number that can only be divided by 1 and itself. The numbers left at the bottom of the tree
Factor
A number that divides evenly into another number. 3 is a factor of 15 (look at the chart!)
Expanded notation
A way of writing a number that shows the place value of every digit
Addition Property of Zero
Adding 0 to any number leaves it unchanged.
Additive Inverse of a Number
Adding the inverse of a number will give you the answer zero. 5 + -5 = 0
a+0=0+a =a
Additive- Identity Property of Zero
18 + 0 = 18
Additive-Identity Property of zero
Multiple
Answers to the Times Tables (eg: Multiples of 3 are: 3, 6, 9, 12, 15 etc.)
a + (b+c) = (a+b) +c
Associative Property
(12+15) + (5+38) = 50 +20

Multiplication identity Property of 1
Multiplication Property of Zero
Multiplying any number by 0 yields 0.
Multiplicative Inverse of a Number
Multiplying the inverse of a number will give you the answer of 1. 1/5 x 5/1 = 5/5 = 1

Identity Property of Multiplication
The product of any number and one is that number.
Order of operations

Identity Property of Addition
The sum of any number and zero is the original number.
Distributive Property
The sum of two numbers times a third number is equal to the sum of each addend times the third number.
Place value
The way that the position of a digit in a number tells us its value
10 Family
This refers to the amount of zeros in a number. We DIVIDE to the left and MUL-TI-PLY-I-I to the right
Associative Property of Addition
When three or more numbers are added, the sum is the same regardless of the grouping of the addends.
Associative Property of Multiplication
When three or more numbers are multiplied, the product is the same regardless of the order of the multiplicands.
Commutative Property of Addition
When two numbers are added, the sum is the same regardless of the order of the addends.
Commutative Property of Multiplication
When two numbers are multiplied together, the product is the same regardless of the order.
