Example 1: Write the Phrase as an Expression 7 increased by a number ________ Negative 14 minus y __________ Negative 19 increased by n __________ The product of 14 and y ______ 10 divided by the sum of a number n and 6 __________ 6 times the quotient of a number x and 3 7 + x -14 - y -19 + n 14y 10_ n + 6 X 3 6

A number more than 7: ________ 7 less than a number: __________ 7 + n The Flipper: Special words that mean you flip the order of the variable (letter) and the number are: More Than Less Than A number more than 7: ________ 7 less than a number: __________ 7 + n 7 - n
