Please Ask My Dear Aunt Sally

Dear Aunt Sally,

My students get confused because I use the phrase “cross multiply” when we are solving proportions and then they want to “cross multiply” when we are multiplying fractions. How do I clear up the confusion?

Chris Cross

Dear Chris,

Your students may not get confused you if you used the phrase “find the cross products” when you are solving proportions, instead of “cross multiply”. I have had students in the past tell me the same thing so I changed the wording that I used when we solve proportions. I learn a lot from my students.

Your Dear Aunt Sally
