Example Questions
Example Question #54 : Operations
Combine like terms and simplify the expression.
The first step is to multiply the expressions in the parantheses:
therefore :
Then place the like variables next to each other:
And simply add the like terms and you have solved the problem:
Example Question #55 : Operations
Reduce the following solution,
The expression is already reduced.
When adding variables, you may only add like variables.
So you add 
Example Question #124 : Ssat Middle Level Quantitative (Math)
Simplify:
Begin by distributing the 
Next, group the like terms:
Finally, combine the like terms:
Example Question #125 : Algebra
Rewrite putting like terms together. There are only two terms with 
Evaluate each set of terms in the parentheses.
There is no other term to group 
Rewrite in simplest form.
Example Question #41 : How To Add Variables
Simplify this mathematical expression.
Rewrite the expression
so that like terms are next to each other.
Evaluate the terms in the parentheses.
The constant is 20.
Rewrite in simplest form.
Example Question #62 : Variables
To simplify this expression,
In this expression, the only terms that can be combined are the ones that have 
Rewrite in simplest form.
Example Question #63 : Variables
Simplify:
Rewrite 
Because the Commutative Property of Multiplication states that (y times z) is equal to (z times y), then 
Evaluate what is inside the parentheses and rewrite in simplest form.
Example Question #64 : Variables
Simplify:
In order to simplify 
Then, evaluate the terms in each parentheses.
When you subtract a negative number, you are adding the inverse. Therefore,
There is nothing to combine the term
Rewrite in simplest form.
Example Question #65 : Variables
Distribute the 
Rewrite.
Then, rewrite the expression putting all like terms together.
Evaluate the terms in the parentheses.
The constant is 18.
Rewrite in simplest form.
Example Question #11 : Expressions & Equations
Simplify the following:
When solving this problem we need to remember our order of operations, or PEMDAS.
PEMDAS stands for parentheses, exponents, multiplication/division, and addition/subtraction. When you have a problem with several different operations, you need to solve the problem in this order and you work from left to right for multiplication/division and addition/subtraction.
Parentheses: We are not able to add a variable to a number, so we move to the next step.
Multiplication: We can distribute (or multiply) the 
Addition/Subtraction: Remember, we can't add a variable to a number, so the
