  5. Subtraction • Difference • Less than • Minus • Decreased by

  6. Multiplication • Times • Product • Multiplied by • Of

  7. Division • Quotient • Divided by • Divided into

  8. Verbal Phrase Expression a. 4less than the quantity6times a numbern b. 3 times the sum of 7 and a number y c. The difference of 22 and the square of a number m

  9. 1. Translate the phrase “the quotient when the quantity 10plus a number xis divided by 2” into an expression.
