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
Example 1
A pin insulator measures 1.312 inches in diameter at the small end and 1.9375 inches at the large end. What is the difference in diameters between the small end the large end?

A pin insulator measures 1.312 inches in diameter at the small end and 1.9375 inches at the large end. What is the difference in diameters between the small end the large end?
Example 2
Correct bearing preload on a differential is obtained when the distance between the bearing caps is 185.5mm. When the mechanic measures the distance, it is 187.43mm. How much more should the bearings be tightened?
Correct bearing preload on a differential is obtained when the distance between the bearing caps is 185.5mm. When the mechanic measures the distance, it is 187.43mm. How much more should the bearings be tightened?
Strategy:
Subtract the correct bearing preload from the current distance. Step 1 Align the decimals vertically, adding zeros if necessary. Step 2 Subtract like whole numbers then drop the decimal straight down. |
