INTEGER
An integer is a number that does not contain a decimal or a fraction.
For example, 4, -23 and 1,569 are all integers. , 3.5 and 66.667 are not
POSITIVE
Positive numbers are numbers greater than zero.

12, 1.8 and are all positive numbers, but of those, only 12 is a positive integer.
NEGATIVE
Negative numbers are numbers less than zero.

For example, -5, -1.3 and -84 are all negative numbers, but only -5 and
-84 are negative integers.
EVEN
Even numbers are integers that are divisible by 2.

For example, 2, -68 and 516 are all even.
ODD
Odd numbers are integers that are not evenly divisible by 2.

Examples of odd numbers include, 5, -13 and 9,871.
CONSECUTIVE
Consecutive numbers are numbers that progress in order at the same interval.

For example, 2, 3, 4 and 5 are consecutive positive integers. -6, -4 and -2 are consecutive negative even integers.
PREMDAS
PEMDAS. What's this?
Well, the order of operations is the order in which you do the math in an equation.
First, you do anything within parentheses.
Next, you calculate any exponents.
Then you do the multiplication and division (working from left to right).
And finally, you do any addition and subtraction (again, working from left to right).

If you have trouble remembering it, try using this mnemonic: Please Excuse My Dear Aunt Sally. You might remember this from grade school
PEMDAS
P PARENTHESIS
E CALCULATE EXPONENTS
M MULT & DIV WORKING LEFT TO RIGHT
D DIVISION
A ADDITION
S SUBTRACTION WORK LEFT TO RIGHT
REMAINDER
The remainder is what is left over after division.

For example, 5 divided by 3 leaves you with a remainder of 2 (3 divides evenly into 5 once, with 2 left over).

If a number divides evenly into another number, you have a remainder of zero.

For example, 100 divided by 20 is 5 with a remainder of 0. 100 divided by 3 is 33 with a remainder of 1
DIVISIBLE
A number is divisible by another number if the second number divides into it evenly (leaving no remainder).

Any even number is divisible by 2. 15 is divisible by 3, but it is not divisible by
RULES OF ZERO
==Zero is a funky number with some pretty funky properties. Here are some helpful rules to remember about zero:
==Zero times any number equals zero.
==Zero is an even integer.
==Zero is neither positive nor negative.
==Zero divided by any number is zero.
==Any number raised to the zero power is equal to 1.
SUM & DIFFERENCE
You calculate a sum by adding.

For example, the sum of 2 and 8 is 10.

The difference is the result of subtraction.

For example, the difference between 96 and 4 is 92.
PRODUCT AND QUOTIENT
You calculate a product by multiplying.

For example, the product of 3 and 6 is 18.

The quotient is the result of division.

For example, if you divide 60 by 12, the quotient is 5.
FACTOR
factor is a whole number that divides evenly into another whole number. A factor can also be called a divisor.

The positive factors of 8 are 1, 2, 4 and 8. The positive factors of 40 are 1, 2, 4, 5, 8, 10, 20 and 40.

Factoid: Every number is a factor of itself.
MULTIPLE
A multiple is the product of the original whole number and any other whole number.

The first 4 positive multiples of 8 are 8, 16, 24 and 32. The first positive multiple of any number is itself.

If you have trouble keeping factors and multiples straight in your mind, remember this: factors are few, while multiples are many.
