Question | Answer |
---|---|
A mathematical language of symbols, including variables | Algebra |
A combination of variables, numbers, and at least one operation | Algebraic expression |
The way in which numbers are grouped does not change the sum or product | Associative Property |
In a power, the number used as a factor. In 10^3, the base is 10. That is, 10^3 = 10 X 10 X 10 | Base |
The numerical factor of a term that contains a variable | Coefficient |
The order in which numbers are added or multiplied does not change the sum or product | Commutative Property |
A term without a variable | Constant |
Choosing a variable and deciding what the variable represents | Defining the variable |
To multiply a sum by a number, multiply each addend by the number outside the parentheses | Distributive Property |
Expressions have the same value, regardless of the values of the variable(s) | Equivalent expressions |
To find the value of an algebraic expression by replacing variables with numbers | Evaluate |
In a power, the number that tells how many times a base is used in a factor. In 5^3, the exponent is 3. That is, 5^3 = 5 X 5 X 5. | Exponent |
The process of writing numeric or algebraic expressions as a product of their factors | Factoring the expression |
The greatest of the common factors of two or more numbers | Greatest common factor |
Properties that state that the sum of any number and 0 equals the number and that product of any number and 1 equals the number | Identity Property |
The smallest whole number greater than 0 that is a common multiple of each of two or more numbers | Least common multiple |
Terms that contain the same variable(s) to the same power | Like terms |
A combination of numbers and operations | Numerical expression |
The rules that tell which operation to preform first when more than operation is used. 1. Simplify the expressions inside grouping symbols 2. Find the value of all powers 3. Multiply and divide in order from left to right 4. Add and subtract in order | Order of operations |
A number expressed using an exponent. The power 3^2 is read “three to the second power”, or “three squared”. | Power |
The status of an expression when it has no like terms and no parentheses | Simplest form |
Each part of an algebraic expression separated by a plus or minus sign | Term |
Variable |
