  3. Variable = a symbol, usually a letter, that represents one or more numbers. Algebraic expression = a mathematical phrase that can include numbers, variables, and operation symbols.

  4. 1. Seven more than n n + 7 2. The difference of n and 7 n - 7 Write an algebraic expression for each phrase.

  5. 3. The product of seven and n 7n 4. The quotient of n and 7

  6. Define a variable and write an algebraic expression for each phrase. Two times a number plus five. Define a variable. Let n = the number Write. 2n + 5 2 * n + 5
