### prime

A ______ number is a positive integer only divisible by 1 and itself
E.g.- 47 can ONLY be divided by 1 and by itself (47)
47/1 = 47
47/47 = 1

### integer

Any of the natural numbers (positive or negative) or zero
E.g.-- -2, -1, 0, 1, 2, 3, etc

### natural

A _______ number is any positive integer or "number" used for counting
E.g.--1, 2, 3, 4, 5, 6, etc

### composite

A ________ number can be divided evenly by numbers other than 1 or itself
E.g.- 48 can be divided by 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

### factor

Any number(s) you multiply together to get another number. Any number that is used to divide a composite number by.
E.g.--The factors of 48 are:
1, 2, 3, 4, 6, 8, 12, 16, 24, 48

### prime

_________ factor is a number that is used to break down a composite number into smaller numbers/divisors
E.g.-The ______ factors of 48 are:
2, 2, 2, 2, and 3
because 2 x 2 x 2 x 3 = 48

### prime

_______ Factorization is the breaking down of a composite number into smaller non-trivial divisors (aka factors), which when multiplied together equal the original integer
E.g.-The ____ factorization of 48 is
2 x 2 x 2 x 3
because 2 x 2 x 2 x 3 = 48

### reciprocal

A ______ or inverse number is related to another number in such a way that when multiplied together their product is 1; Basically the opposite, particularly in fractions
E.g.-- 3/4 and 4/3 are reciprocals of each other

### inverse

A multiplicative _______ is one of a pair of numbers whose product is 1
E.g.--The reciprocal of 2/3 is 3/2 because
2/3 multiplied by 3/2 = 1

### inverse

An additive _________ is an integer and its opposite whose sum is zero
E.g.-- -2 + 2 = 0

### LCM

Least Common Multiple is the smallest number that is a multiple of two or more numbers.
E.g.-The ___ of 3 and 5 is 15
because 15 is a multiple of 3 and also a multiple of 5. Other common multiples include 30 and 45, etc, but they are not the smallest (least).

### GCF

Greatest Common Factor is the highest/largest number that divides exactly into two or more numbers. It's the "greatest" thing for simplifying fractions!
E.g.-The ____ of both 12 and 30 is 6. 12 and 30 can also both be divided by 1, 2, 3, but 6 is the largest number

### Fraction

A small part or item forming a piece of a whole
E.g.-- 3/4 is a _________

### decimal

A _______ number is any number that is related to a fraction amount. It is marked by a decimal point.
E.g.--- 0.75 is a ________ number

### inequalities

Any mathematical sentence(s) involving <, >, or = plus < or >
E.g.- 3 is greater than 1
so that the inequality is: 3 > 1
