Add and subtract fractions. Simplify answers. Compute with mixed numbers. In arithmetic, we add, subtract, multiply, and divide natural numbers: 1, 2, 3, 4, 5, and so on. Assuming that you have mastered those skills, we will now review the arithmetic of fractions. Factor and Prime Factor Natural Numbers. To compute with fractions, we need to know how to factor natural numbers. To factor a number means to express it as a product of two or more numbers. For example, some ways to factor 8 are The Language of Algebra When we say “factor 8,” we are using the word factor as a verb.

Since b represents the number of bicycles to be manufactured, we use it as the heading of the first column. Since t represents the number of tires needed, we use it as the heading of the second column. Then we enter the size of each production run in the first column, as shown. Bicycles to be Tires manufactured to order b t The Language of Algebra To substitute means to put or use in place of another, as with a substitute teacher. Here, we substitute 233 and 852 for b. 233 466 852 1,704 Step 2: We substitute 233 and 852 for b in t ϭ 2b and find each corresponding value of t .
