The absolute value of positive number is the number itself, so 
Example Question #22 : 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 #21 : Operations With Negative Numbers
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 #23 : Operations With Negative Numbers

The answer is:
Example Question #21 : Operations With Negative Numbers
Simplify the following:
Begin by simplifying everything that is found in parentheses:
Next, perform the subtraction in the numerator:
Although you cannot simplify the fraction, you can cancel out the negatives since you have a negative in both the numerator and the denominator. Thus, your answer is:
Example Question #308 : Ged Math
Simplify the following:
Okay, this is complex. However, just do it step by step and you will surely get it correct! First, handle everything in parentheses:
Next, simplify each of the smaller fractions:
Now, remember that to divide two fractions, you need to multiply by the reciprocal, this means:
You don't have to do any more work, however! The answer is, of all things, 
Example Question #26 : Operations With Negative Numbers
