# 7th Grade Math / Lesson 4: Translating

 TRANSLATING What will we be learning in this unit? This unit will review some basic terms and concepts needed to continue through this math class. Today's lesson will cover translating expressions and equations.

 TRANSLATING Translating is changing from one form to another. (from written words to algebra form or from algebra form to written words) Examples:1. The product of 3 and a number translates to 3x.2. Four is equal to the difference of 10 and a number translates to 4 = 10 - x. 3. Three more than a number is 10 translates to X + 3 = 10.

 TRANSLATING Important words to use know when translatingAddition: increased by                                Subtraction: decreased by                plus                                                                     minus                 sum                                                                    difference                more than                                                           less than  Multiplication: product                               Division: quotient                          multiplied by                                         divided by                          times                              Equal sign:    equals                                 Variable: a number                       is equal to                                            some number                       is                                                          what number

 TRANSLATING PracticeTranslate the following. 5 more than a number. 12 is equal to the product of 3 and 4. A number decreased by 6.

 TRANSLATING PracticeTranslate the following. 5 more than a number.                           X + 5 12 is equal to the product of 3 and 4.    12 = 3 * 4 A number decreased by 6.                     Y - 6
