- What is a variable?
- A letter representing an unknown number or value
- What is a coefficient?
- The number multiplied by a variable in a term
- Define a term in algebra
- A number, variable, or product of numbers and variables
- What is an expression?
- A mathematical phrase with numbers, variables, and operations, but no equal sign
- What is an equation?
- A mathematical statement showing two expressions are equal, with an equal sign
- What are like terms?
- Terms with the same variable(s) raised to the same power(s)
- What does combining like terms mean?
- Adding or subtracting terms with identical variables and exponents
- What is PEMDAS?
- Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right)
- State the distributive property
- a(b + c) = ab + ac; multiply the factor outside by each term inside
- What is the commutative property of addition?
- a + b = b + a; the order of addends does not affect the sum
- What is the associative property of addition?
- (a + b) + c = a + (b + c); grouping does not affect the sum
- What is the additive identity property?
- a + 0 = a; adding zero to any number leaves it unchanged
- What is the additive inverse property?
- a + (-a) = 0; a number plus its opposite equals zero
- What is a linear equation?
- An equation where the variable has an exponent of 1; its graph is a straight line
- What is a quadratic equation?
- An equation where the highest exponent of the variable is 2
