Remember that like terms are terms with the exact same variable part.

**Add the polynomials**.

**Subtract the polynomials**.

We may encounter function notation,

**For the given functions find (**.

Adding polynomials requires us to first identify then combine like terms.

Remember that like terms are terms with the exact same variable part.

**Add the polynomials**.

When subtracting polynomials you distribute the negative one first and then identify and combine like terms.

**Subtract the polynomials**.

We may encounter function notation,

In this case, just add or subtract the given polynomials as we did in the above examples.

**For the given functions find (***f* + *g*)(*x*) and (*f* - *g*)(*x*).

When several operations are to be applied within a calculation, we must follow a specific order to ensure a single correct result.

**Order of Operations**:

**Caution**: Please do not dismiss the fact that multiplication and division should be worked from left to right. Many standardized exams will test you on this fact. The following example illustrates the problem.

**Simplify**.

Order of operation problems get a bit more tedious when fractions are involved. Remember that when adding or subtracting fractions you need to first find the equivalent fractions with a common denominator. Multiplication does not require a common denominator.

**Simplify**.

We will see that some of the problems have different looking parentheses { [ ( ) ] }, treat them the same and just remember to perform the*innermost parentheses first*. Some problems may involve an absolute value, in which case you will need to apply the innermost absolute value first as you would if it were a parentheses.

**Simplify**.

**Video Examples on YouTube**:

- Perform all calculations within the innermost Parentheses first.
- Evaluate Exponent expressions.
- Apply the Multiplication and Division operations from left to right.
- Lastly, work all Addition and Subtraction operations from left to right.

To avoid these unnecessary mistakes, work one operation at a time and for each step rewrite everything. This may seem like a lot of work but it really helps avoid errors.
