Example Questions
Example Question #36 : Operations With Negative Numbers
Evaluate:
Evaluate using order of operations first. Double negatives will turn into a positive.
Determine the sum.
The answer is:
Example Question #37 : Operations With Negative Numbers
Solve:
Expand the expression by order of operations.
The answer is:
Example Question #153 : Basic Operations
Solve:
Solve by first evaluating the parentheses. Double negatives result in a positive sign, while a positive and negative sign will result in a negative sign.
Simplify the terms so that there is one sign remaining for each integer.
Evaluate the sum.
The answer is:
Example Question #38 : Operations With Negative Numbers
Evaluate:
Evaluate the terms of the inner parentheses.
Double negatives translates to a positive sign.
The answer is:
Example Question #41 : Operations With Negative Numbers
Simplify:
Evaluate by using the order of operations. Double negatives result into positive.
Evaluate the sum.
The answer is:
Example Question #41 : Operations With Negative Numbers
Solve:
Simplify the signs first. Double negatives result in a positive.
The answer is:
Example Question #157 : Basic Operations
Simplify the following expression:
Simplify the following expression:
We are dealing with a complex series of negative numbers. We have to combine these accurately to get the correct answer.
Let's deal with the first two terms. When subtracting from a negative number, we are essentially adding a negative to an already negative number. Therefore,
Which can be combined to get:
Now, we need to deal with the third term. Subtracting a negative is the same as adding a postive (recall that two negative signs make a positive).
So, our final answer is 10
Example Question #41 : Operations With Negative Numbers
Evaluate:
A negative number raised to an even-numbered power is equal to the absolute value of the number taken to that power. Therefore,
This number is equal to 4 taken as a factor four times, so
Example Question #41 : Operations With Negative Numbers
What is the value of the expression 
To find the value of 
For 
Now, follow the order of operations to simplify. Tackle the exponent first.
Next, multiply.
Finally, subtract.
Example Question #151 : Basic Operations
Add the equation:
Adding negatives is the same as subtracting. This is because we are adding negative numbers to our positive number, which in turn will make it smaller than when we originally started.
Let's take 
We have counted
