Example Questions
Example Question #345 : Operations And Properties
Evaluate:
In this scenario, we have to first simplify the absolute value, and then eliminate the double negatives.
Eliminate the absolute value. The value inside will become positive.
Combine double signs into one sign.
Example Question #345 : Operations And Properties
Solve the absolute value:
Evaluate the quantity inside the absolute value, and then solve.
Example Question #32 : Absolute Value
Simplify the absolute value:
First evaluate the terms inside the absolute value.
The absolute value bars make the value inside of them positive.
Simplify the absolute value.
Example Question #346 : Operations And Properties
Solve:
Quantities inside an absolute value will be converted to a positive value.
In this particular case the negative sign is outside of the absolute value bars and thus the bars can be dropped. Once the absolut value bars are dropped, work from left to right to solve.
Example Question #351 : Operations
Solve the expression:
To solve this, first evaluate the terms inside the absolute values.
Recall that any value inside an absolute value sign will become positive and the absolute value bars will go away.
Simplify.
Example Question #352 : Operations
Solve:
Solve by evaluating the quantity inside the absolute value.
Remember that the absolute value bars will turn any value inside of them to a positive value.
Now simplify the absolute value, and apply order of operations.
Example Question #31 : Absolute Value
Solve:
Simplify the terms inside the absolute value.
Negative and positive values inside the absolute value will become positive.
Example Question #354 : Operations
Solve:
Evaluate by first eliminating the absolute value. Any positive or negative value inside the absolute value will be converted to a positive value.
The exponents can be expanded.
Multiply the terms and subtract.
The answer is 
Example Question #355 : Operations
Solve the absolute values: 
Simplify the numbers inside the absolute value first. Do not distribute the negative signs into the absolute value. Values inside the absolute value sign are converted to positive values.
Simplify the above expression.
Subtract the values.
Example Question #356 : Operations
Determine the value of:
Evaluate the quantity that is squared.
Any value inside the absolute value sign will be converted to a positive number.
The answer is:
