Definitions (1)
the greatest number that is a factor of two or more numbers
GCF (greatest common number)
The smallest whole number greater than 0 that is a common multiple of each of two or more numbers.
LCM (least common multiple)
Numbers that can be multiplied together to get another number
factors
The line on a graph that runs horizontally (left-right) through zero.
x-axis
A whole number that can be made by multiplying other whole numbers.
composite number
a number less than zero; located to the left of 0 on a number line
negative number
The result of multiplying a number by an integer (not by a fraction)
multiple
a number higher than zero
positive number
a combination of numbers, integers combined using mathematical operators such as addition, subtraction, multiplication, or division, with no "equals" sign (=)
numerical expression
says how many times to use that number in a multiplication. It is written as a small number to the right and above the base number.
exponent/power
two numbers that have the same absolute value but have different signs
opposites
any number that can be written as a fraction
rational number
A decimal number that has digits that end
terminating decimal
Finding which prime numbers multiply together to make the original number.
prime factorization
The number that gets multiplied when using an exponent.
base
a number that isn't a decimal, fraction or negative number
whole number
A decimal number with a digit (or group of digits) that repeats forever (usually have to round)
repeating decimal
The starting point
origin
an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations.(ex. 3x² − 2xy + c)
algebraic expression
A whole number greater than 1 that can not be made by multiplying other whole numbers.
prime number
All whole numbers (both positive and negative) and zero
integers
A coordinate system formed by the intersection (0) of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.
coordinate plane
A statement that compares two quantities using <, >, ≤,≥, or ≠
inequalities
Any of the 4 areas made when we divide up a plane by an x and y axis, as shown. They are usually numbered I, II, III and IV.
quadrant
The line on a graph that runs vertically (up-down) through zero.
y-axis
