Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.

Step-by-step explanation:

Giving the following information:

Manager at Shop & Save Grocers= Hourly wages $16.50 per hour

Assistant Manager at Unbelievable Toys= Monthly wages $3,800

Cashier at 7-12 Convenience Store= Yearly wages $43,000

First, we need to calculate the yearly wages, and then compare the results:

Shop & Save Grocers= (16.5*40)*52= $34,320

Unbelievable Toys= 3,800*12= $45,600

The highest paying job is at Unbelievable Toys.

Difference= 45,600 - 34,320= $11,280
