Translating Verbal Phrases into Expression

Order is always left to right EXCEPT words with “than” Key Add Subtract Multiply Divide Add More than; sum of; greater than; added to; increased by, plus Subtract Less than; fewer than; subtracted from; minus; difference of; decreased by Multiply Times; product of; multiplied by; “double” or “twice” means 2 times; half of means to multiply by 1/2; Divide Divided by; quotient of; Order is always left to right EXCEPT words with “than”

To show work…. Underline each word and translate the English into math Put it all together at the end for your final answer

Ex 1: The difference of a number and 8

Ex 2: 7 less than a number n - 7

Ex 3: The sum of a number and 14

Ex 4: The quotient of a number and 4

Ex 5: Write a numerical expression for each verbal phrase: The cost of six electronic handheld games if each costs eight dollars
