Write Algrebraic Expressions Translating verbal expressions into algebraic expressions is an important algebraic skill. Example: Write an algebraic expression for each verbal expression. a. four more than a number b. the difference of a number squared and 8 n The words imply addition. The expression implies subtraction. more than difference of four more than a number the difference of a number squared and 8 n 4 + 8 n – The algebraic expression is 4 + The algebraic expression is 8. n. – Exercises Write an algebraic expression for each verbal expression. 1. a number decreased by 8 a number divided by 8 2. a number squared 3. 4. four times a number 5. a number divided by 6 6. a number multiplied by 37 7. the sum of 9 and a number 8. 3 less than 5 times a number 9. twice the sum of 15 and a number 10. one-half the square of b 11. 7 more than the product of 6 and a number 12. 30 increased by 3 times the square of a number
