    Four times the quantity six plus two

    six plus two: 6 + 2 Four times the quantity six plus two 4(6 + 2) <-- This is our algebraic expression If we need to evaluate this, we have: 4(8) 32

    Six less two

    less means subtract: 6 - 2 <-- This is our algebraic expression If we need to evaluate we have: 6 - 2 = 4

    Nine less than twelve

    less than means we subtract 9 from 12: 12 - 9 <-- This is our algebraic expression IF we want to evaluate this, it's: 12- 9 = 3
