    Algebraically, where | denotes concatenation, and z is a string of 0s: x = y | 1 | z -x = ~x + 1 -x = (~y | 0 | ~z) + 1 -x = ~y | 1 | z x & -x = (y & ~y) | (1 & 1) | (z & z) x & -x…

    As an math educator, I think there's a huge flaw in this study. The investigators failed to follow up to see why the mistake was made. They leap to assuming the player is trying to…

    the kids are alright. Reminds me of when I organized a real life version of Pac-Man on the quad in 2006, inspired by this game ran on the streets of Manhattan in 2004. https://www.…

    Nice to see JRMF trending on HN. JRMF puzzles and festivals are a great way to engage general audiences of grade school students in mathematical inquiry and problem solving.

    I like the phrasing used by https://houseofgraphs.org/ — while there are an infinite number of mathematical objects in any category, there are only "a few thousand that can be cons…
