Key Terms
- coefficient
- The constant that multiplies the variable(s) in a term is called the coefficient.
- composite number
- A composite number is a counting number that is not prime.
- divisibility
- If a number is a multiple of , then we say that is divisible by .
- equation
- An equation is made up of two expressions connected by an equal sign.
- evaluate
- To evaluate an algebraic expression means to find the value of the expression when the variable is replaced by a given number.
- expressions
- An expression is a number, a variable, or a combination of numbers and variables and operation symbols.
- least common multiple
- The smallest number that is a multiple of two numbers is called the least common multiple (LCM).
- like terms
- Terms that are either constants or have the same variables with the same exponents are like terms.
- multiple of a number
- A number is a multiple of if it is the product of a counting number and .
- prime factorization
- The prime factorization of a number is the product of prime numbers that equals the number.
- prime number
- A prime number is a counting number greater than 1 whose only factors are 1 and itself.
- solution of an equation
- A solution to an equation is a value of a variable that makes a true statement when substituted into the equation. The process of finding the solution to an equation is called solving the equation.
- term
- A term is a constant or the product of a constant and one or more variables.
