Application
Most math problems that you will encounter in the workplace do not come written with the appropriate operator (+. -, ÷, or x) in place. As an employee, you will need to decode the real life problem into an algorithm. Words used that typically indicate subtraction are:
DIFFERENCE
DECREASE
MINUS
LESS THAN
LOSS
FEWER
LEFT
REMAINING
Examples
1. You have $304 in your checking account. If you write a check for $139, how much is left in your account?
304 - 139 = $165
2. A total resistance of 60 megohms is needed. On hand there are resistors with the following values: 14 megohms, 25 megohmsm, and 11 megohms. What is the difference between what is needed and what is on hand?
First find the total of the resistors on hand:
14 + 25 + 11 = 50 megohms
Calculate the difference between the needed megohms and resistors on hand.
60 - 50 = 10 megohms
