Rational numbers
Largest number system
Rational numbers
Can be expressed as a fraction. 4 = 4/1. Also decimals that end or continue forever repeating.
Real numbers
Any number; Include zero, negative and positive integers.
Real numbers are considered this.
continuous and can be measured.
Discrete data
counted; doesn't allow for values between.
Every positive whole number has two square roots.
True
Identity Property
Property that 0 can be added to any number without changing the value of the number. Likewise, 1
can be multiplied by any number without changing the value of that number.
Factor
An integer that divides another integer. We say an integer, x, is a factor of another integer, y, if the
quotient y/x is also equal to an integer.
Fundamental Theorem of Arithmetic
Concept which states that any integer greater than 1 is either prime or is the product of a unique set
of prime numbers.
Factorization
Process of determining the prime factors of a composite number.
data
Values; qualitative or quantitative.
Square root
is only a real number
base
number of outcomes
, Percentage proportion is always set up to express percentage value
over 100
conditional proportion
proportion where one part of a proportion is a variable, or unknown quantity.
cross multiplying
method used to prove that a proportion is true.
rate
ratio that compares two quantities having different units of measure.
unit multiplier
fraction that contains two equivalent quantities but in two different units, used in order to convert
units.
unit conversion
method used to change between measurement systems.
all real numbers with a fixed value, prime, composite, odd, even, rational, or irrational.
constants
0
expression known as a constant.
1
expression known as linear.
2
expression known as quadratic.
3
expression known as cubic.
False
Process for undoing multiplication and division operations will always work, even if one of the
numbers is zero.

1
root of a number
