Write down how many hours you worked last week. At the end of this week, write down how many hours you worked this week. Use a variable to represent the hourly wage and write an algebraic expression to calculate your paycheck for the two-week period. Simplify the expression.

For example, suppose you were asked to simplify the following expression: 3+4·2+5 At first glance, you might think it is easy: 3 + 4 = 7 and 2 + 5 = 7, then 7 · 7 = 49. Another person might say 3 + 4 = 7 and 7 · 2 = 14 and 14 + 5 = 19. Actually, both of these answers are wrong! To eliminate the possibility of getting several answers for the same problem, there is a specific order you must follow. This specific order is called order of operations and the steps you follow are: 1. Perform the operations inside grouping symbols such as ( ), { }, and [ ].
