\(\begin{array}{c}\left(3\cdot\frac{1}{3}\right)-\left(8\div\frac{1}{4}\right)\\\text{}\\=\left(1\right)-\left(8\div \frac{1}{4}\right)\end{array}\), \(\begin{array}{c}8\div\frac{1}{4}=\frac{8}{1}\cdot\frac{4}{1}=32\\\text{}\\1-32\end{array}\), \(3\cdot \frac{1}{3}-8\div \frac{1}{4}=-31\). We will use the distributive property to remove the parentheses. 30x0=0 20+0+1=21 Click here to get your free Multiplying Exponents Worksheet.

Addition/subtraction are weak, so they come last. Add numbers in the first set of parentheses. In the following example, you will be shown how to simplify an expression that contains both multiplication and subtraction using the order of operations. Rewrite in lowest terms, if needed. We combined all the terms we could to get our final result. For example, when we encounter a number Since there are an odd number of negative factors, the product is negative. Exponents, unlike mulitiplication, do NOT "distribute" over addition. Absolute value expressions are one final method of grouping that you may see. Additionally, David has worked as an instructor for online videos for textbook companies such as Larson Texts, Big Ideas Learning, and Big Ideas Math. In the following video you are shown how to use the order of operations to simplify an expression that contains multiplication, division, and subtraction with terms that contain fractions. "This article was a nice and effective refresher on basic math. This material is based upon work supported by the National Science Foundation under NSF Grant No. In practice, though, this rule means that some exercises may be a lot easier than they may at first appear: Who cares about that stuff inside the square brackets?
