Math Words
| Term | Definition |
|---|---|
| Rational Number | Any number that can be written as a fraction |
| Integer | Any whole number and it's opposite |
| Oppsites | Two numbers the same distance from zero in opposite directions from zero |
| Absolute Value | The distance the number is from zero (ALWAYS POSITIVE) |
| Terminating Decimal | A decimal that ends |
| Repeating Decimal | A decimal that repeats Uses bar notation to write |
| Exponent | An exponent is a small number written with another big number that tells how many times to multiply the big number by itself |
| Base | The number that is going to be raised to a power. |
| Factor | To factor a number means to break it up into numbers that can be multiplied together to get the original number. |
| Perfect Square | A number made by squaring a whole number. |
| Order of Operations | order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction". |
| Numerical Expressions | numerical" means "involving numbers" and the term "expression" means "phrase". A numerical expression is a mathematical phrase involving only numbers and one or more operational symbols |
| Algebraic Expressions | algebraic expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide) |
| Variable | the dependent variable y represents the value of a function of x. To simplify formulas, it is often useful to use the same symbol for the dependent variable y and the function mapping x onto y. |
| Constant | a constant is a number on its own, or sometimes a letter such as a, b or c to stand for a fixed number. If it is not a constant it is called a variable. |
| Coefficient | a numerical or constant quantity placed before and multiplying the variable in an algebraic expression |
| Term | terms whose variables (and their exponents such as the 2 in x2) are the same. |
| Expression | expression is a mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add,subtract,multiply, and divide) |
| Equation | An equation says that two things are equal. So an equation is like a statement "this equals that" |
| Distributive Property | Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". |
| Term | A Term is either a single number or a variable, or numbers and variables multiplied together. |
| Coefficent | A Coefficient is a number used to multiply a variable |
| constant | A term without a variable |
| Like terms | "Like terms" are terms whose variables (and their exponents such as the 2 in x2) are the same |
