Example Questions
Example Question #24 : Negative Numbers
Solve:
Remember that subtracting a negative number is just like adding the positive of that number, because you move to the right (more positive) on the number line. Therefore
Example Question #2 : Subtract Rational Numbers And Understand The Absolute Value Of Their Difference: Ccss.Math.Content.7.Ns.A.1c
Subtract:
Distribute the negative sign through the parentheses. Double negatives equal a positive.
The answer is 
Example Question #243 : Operations
Solve:
To evaluate this, first simplify the innermost parentheses.
Distribute the negative two in front to term inside the parentheses.
Example Question #1261 : Pre Algebra
Evaluate:
Break up the parentheses. Double negatives result in a positive sign, and positive with a negative sign will result in a negative sign.
Next, simplify by adding and subtracting each component from left to right.
Example Question #251 : Operations And Properties
Solve:
Use the order of operations to solve this. A negative number that is not in parentheses squared will remain negative.
Example Question #252 : Operations And Properties
Simplify:
