Example Question #131 : Basic Operations
An airplane takes off from Death Valley, which is 282 feet below sea level. It ascends 12,879 feet before leveling off, then it descends another 1,276 feet; it finally ascends 4,874 feet. Which of the following expressions is equal to the plane's current elevation in feet?
The initial elevation of the plane is 282 feet below sea level, which is 
This expression is
Example Question #131 : Basic Operations
Evaluate without the aid of a calculator:
Since absolute value bars are grouping symbols, we first raise 
The absolute value of a negative number is the corresponding positive, so
Example Question #13 : Operations With Negative Numbers
An airplane takes off from Death Valley, which is 282 feet below sea level. It is now flying at an elevation of 
We are looking for the difference between the current elevation of the plane and the initial elevation, so we subtract initial elevation

The absolute value of a negative number can be determined by removing the negative symbol, so 
Example Question #21 : Operations With Negative Numbers
An airplane takes off from Death Valley, which is 282 feet below sea level. It ascends 12,879 feet before leveling off, then it ascends 4,276 feet; it finally descends 1,874 feet. Which of the following expressions is equal to the plane's current elevation in feet?
The initial elevation of the plane is 282 feet below sea level, which is 
This expression is

The absolute value of positive number is the number itself, so 
Example Question #23 : Operations With Negative Numbers
Evaluate:
Do not use a calculator.
To divide two numbers of like sign, just divide their absolute values; their quotient will be positive.
Example Question #303 : Ged Math
Solve:
When a negative number is subtracted with a positive number, we will have an increasingly negative number.
Double negative signs will translate into a positive sign.
Sum the two numbers.
The answer is:
Example Question #24 : Operations With Negative Numbers
Solve:
Evaluate the terms in the parentheses first. Double negatives will turn into a positive.
Simplify this expression.
The answer is:
Example Question #25 : Operations With Negative Numbers
Evaluate:
A positive and a negative sign will be combined as a negative.
When a negative number is subtracted, it becomes increasingly negative.
The answer is:
