Multiplying VariablesMore Than One VariableIn a problem like the one below, the terms cannot be multiplied by simply adding exponents because each multiplier is a different letter variable. y^{5} * x^{2} To show the answer to this problem, you simply remove the multiply sign and put the terms next to each other, and in alphabetical order: x^{2}y^{5} Look over the next problem. x^{2} * x^{3}y^{2} As you can see, in this problem the x^{2} is multiplying a term which has a variable x, and a variable y. The result of this multiplication is found using a combination of the two previously presented techniques. We begin by adding the exponents of x^{2} and x^{3}: 2 + 3 = 5, therefore the product will contain x^{5}. Now since a y is present in the second term but not the first, it is simply copied into the result. Thus the answer is: x^{5}y^{2} The next page lists some calculators and worksheets that are related to this lesson.
