# Word Problems Terms

## Get down with the lingo

The number that when added to the given number results in the additive identity 0. The additive inverse of x is -x, as x + (-x) = 0.

### Algebraic Expressions

An expression that contains one or more terms and operations to combine them. Each term contains variable(s), constant(s), or a product of variables and constants.

### Coefficient

A number or a constant multiplied by a term in an algebraic expression. Coefficients always go first. Or is that "ladies"…?

### Constant

A value that does not change. Stay gold, Ponyconstant!

### Dependent Variables

A variable in a function that changes due to the independent variable.

### Distributive Property

The rule where multiplication of numbers distributes over addition and subtraction: a(b ± c) = ab ± ac. Start distributin' the news.

### Equivalent Equations

Two different pairs of equations that have the same solution(s).

### Factoring

Breaking up an algebraic expression into two or more expressions that can be multiplied together to get the original expression.

### Independent Variables

Variables in a function that assume values freely or independently.

### Inequality

A relation between two unequal algebraic expressions using the symbols <, >, ≤, and ≥.

### Like Terms

Two terms that have the same variables raised to the same exponent. Like terms may have different coefficients.

Four times a number.

### Solution

The value(s) of variable(s) that satisfy an equation or inequality.

### Variable

A value that changes. Variables are commonly represented by the letters x, y, or z.
