In reply to Unknown. N/O is correct (until you come to calculus), O/K is incorrect as 0/0 is also a no and it isn't apparent if you just have this poster.

Sorry, but N/0 = undefined is WRONG.
0/0 = undefined (undefined means that any result number works, indeed 0=A*0 for any A)
but
3/0 is impossible instead (no result work, indeed 3=A*0 is not true for any number A)

You didn’t include a poster showing zero simultaneously in the numerator and denominator as a fraction. That fraction is considered undetermined because you’re not dividing anything at all and therefore have no clue what you might’ve actually started with since any number times zero will equal zero. I guess you either couldn’t make a clever reminder or didn’t know that “zero divided by zero” was (and still is) supposed to be called the undetermined fraction.

i just found your site and i just want to say THANK YOU!!! i'm tearing my hair out with my students this semester…i teach a transition-to-college program for adults, and have a lot of struggling math-phobes in my class. usually things go pretty well, but something just isn't clicking for this cohort. i'm SO EXCITED to try some of your ideas! i think they will be AMAZING for my visual learners! i can't believe you are just putting all this out there for free…your hard work is much appreciated, and if you wrote a book i would buy it 🙂
