Kimberly; the Associative Property only holds true if all numbers are added or all numbers are multiplied, not a combination of the two. Additive Identity Property 7. Since the order in which the costs are added does not matter, the Commutative Prop. By adding 4 and 26, the result is 30, and 30 12 is

Addition and subtraction Let's look at a problem to see how this works. In this equation, you'd start by simplifying the part of the expression in parentheses: According to the order of operations, next we'll simplify any exponents.

There's one exponent in this equation: Next, we need to take care of the multiplication and division. We'll do those from left to right: All that's left is the last step in the order of operations: Our expression has been simplified—there's nothing left to do.

Remember, you must follow the order of operations when you're performing calculations—otherwise, you may not get the correct answer.

Still a little confused or need more practice? We wrote an entire lesson on the order of operations. You can check it out here.

Adding like variables To add variables that are the same, you can simply add the coefficients. To multiply variables with coefficients, first multiply the coefficients, then write the variables next to each other.

So what's our first step? As you might remember, the 3 on the outside of the parentheses means that we need to multiply everything inside the parentheses by 3. There are two things inside the parentheses: We'll need to multiply them both by 3.

We can rewrite the expression as: Assessment Want even more practice?
