This two page free math resource is a sequential step-by-step explanation of why you cannot divide by zero. It starts off by explaining what division is and how it relates to multiplication. It concludes with a simple visual to help the students remember the difference between 0 being in the numerator and 0 being in the denominator.
I created this resource because one day, a student of mine, a mathphobic to be sure, asked, “Why can’t I divide by zero?” Promptly I gave him the answer that any good mathematician would, “You can’t divide by zero because zero is undefined. It just cannot be done.” Well, that went over like a lead balloon; so, I knew it was time to sit and down and write out a plausible but understandable explanation that my students could understand.
This is just one part of a 15 page resource called Six Difficult Math Questions with Answers.
