Adding and subtracting negative integers is confusing if you don't use parentheses right. As long as you remember to keep them in the right places and stay neat, it is easy. Subtracting negative numbers is the same as adding a positive number, and adding a negative number is the same as subtracting a positive number. So, we could rewrite the equation like this:
Example Question #2 : How To Combine Like Terms With Negative Numbers In Pre Algebra
What is 
To simplify a problem like the example above we must combine the like termed variables.
Like terms are the numbers that have the same variable, in this example, 
Separate the
Then perform the necessary addition to get
Then separate the
Then perform the necessary subtraction to get
We then combine our answers to have the simplified version of the equation 
Example Question #3 : How To Combine Like Terms With Negative Numbers In Pre Algebra
If 
Let's start with our equation, 
Subtract 
Combine our 
Divide both sides by 
However, the problem is asking for 
Example Question #92 : High School Math
Simplify the following equation by combining like terms:
X is the only term that appears twice in the equation. Since both are positive numbers, we can add the X terms to simplify the equation.
Example Question #5 : How To Combine Like Terms With Negative Numbers In Pre Algebra
Combine the like terms for 
Remember, adding a negative number is the same as subtracting a positive number. That means we can think of this problem as 
If we think of this on a number line, we start at 
Example Question #96 : High School Math
Simplify:
Here, we are interested in combining like terms. Like terms are those with the same variable,.
When combining terms with 
Therefore, we have 
Example Question #1 : How To Combine Like Terms With Negative Numbers In Pre Algebra
Simplify:
Combine like terms:
= (5 + 7) + (-2x - 4x - 9x)
= 12 + (-15x)
= 12 - 15x
