Title: Dividing by zero problems in this deck
Review: The cards are nice and sturdy, but I noticed that in whatever universe the publisher lives in, it must be possible to divide by zero. It did provide an interesting and humorous teaching moment with my daughter, but mistakes like this are pretty much unacceptable in a teaching aid. (See example from my deck: [...]). If you're looking for division cards that are correct, you may wish to keep looking.
