Ignore?
power
a number produced by raising a base to an exponent
exponent
A mathematical notation indicating the number of times a quantity is multiplied by itself
Base
the number that is written with an exponent
For all real numbers x, y, and z, if x = y, then x + z = y + z.
algebraic expression
An expression consisting of one or more numbers and variables along with one or more arithmetic operations
Coefficient
the decimal part
Composite number
a number with more than two factors.
constant
A value that does not change.
Division Property of Equality
For all real numbers x, y, and z, if x = y, and z ≠ 0, then x/z = y/z. You can divide each side of an equation by the same non-zero number and not change its truth value.
Equation
A mathematical sentence that contains an equals sign
Evaluate
To find the value of a mathematical expression.
greatest common factor
The greatest factor that two or more numbers share.
inverse operations
operations that undo each other
Isolate the variable
To get a variable alone on one side of an equation or inequality in order to solve the equation or inequality.
least common multiple
The smallest multiple (other than zero) that two or more numbers have in common.
Like Terms
expressions that contain the same variables to the same power
multiple
Answers to the Times Tables (eg: Multiples of 3 are: 3, 6, 9, 12, 15 etc.)
Multiplication Property of Equality
For all real numbers x, y, and z, if x = y, then xz = yz.
numerical expression
A mathematical phrase that has a combination of numbers and at least one operation
order of operations
The rules for calculating a maths question containing mixed operations, such as 14 - 2 x 4 + 12
prime factorization
Breaking down a composite number until all of the factors are prime
Prime number
A number that can only be divided by 1 and itself. The numbers left at the bottom of the tree
Scientific notation
where a number is written into 2 parts first just the digits (with decimal point after first digit) followed by ×10 to a power
Solution
The value or values that make an equation or inequality true.
solve
The process used to find the value or values that make an equation true.
standard form
the number written with digits
Subtraction Property of Equality
For all real numbers x, y, and z, if x = y, then x - z = y - z.
term
An element or number in a sequence.
Variable
an alphabetic character representing a number, called the value, which is either arbitrary or not fully specified or unknown. It is usually a letter like x or y.
verbal expressions
A word or phrase.
sum
