A strange little side quest
Between one round of Resolve a Math and the next, this is worth knowing: The first crossword puzzle book appeared in 1924 in a cautious initial printing of 3,600 copies, complete with a free pencil. And then there is this: Space Invaders, released in 1978, helped push video games into mainstream popular culture. So a round of Resolve a Math is not just a quick distraction; it is a tiny stop on a much longer puzzles timeline.
