Multiplication Puzzle!
Hello mathematicians, puzzlers, and other curious people! Have you seen puzzles like this one? Take a minute (or a little longer) to try to solve it. If you\’d like to see how I dealt with it, and some questions I raised along the way and afterward, check out this video: Calc You Later!
Calculus Formula Puzzle
Hello mathematicians, puzzlers, and other curious people! For those of you who are learning calculus, do you miss how games used to be part of your lessons? Here\’s a jigsaw puzzle of an important calculus formula so you can study while you put it together. (Click the picture to go to the actual puzzle.) I…
Whopper of a Puzzle
Hello mathematicians, puzzlers, and other curious people! (Content notice: not-quite-spoilers for a puzzle at a well-known fast food burger chain.) In this video I combine summation notation, powers of -1, fractional exponents, factorials, and a few other things along the way, to solve a whopper of a problem. I hope you enjoyed sinking your teeth…

Like I mentioned, there are still some directions available for further exploration, so I don\’t think we\’re done yet with this puzzle and ones like it. But, for now, Calc You Later!
A simple-looking puzzle
Hello mathematicians, puzzlers, and other curious people! Similar to crosswords but with numbers, intersecting math facts can form puzzles. Here\’s an example. While completing this puzzle is straightforward for most mathematicians, setting up more puzzles of the same kind is more complicated. For example, if the middle number were 2 instead of 3 and the…
