          additional info
          • not all puzzles are solvable.
          • 0^0 = 1 and 0! = 1.
          • the calculator is an edited version of math-expression-evaluator to use decimal.js (this was vibe coded with google gemini).
          • animation generator uses jsgif.
          • emoji explanations:
            💥 - too many digits of precision / number too large during calculation
            ❓ - general error
            ♾️ - divide by zero
            🌀 - multiple results in multisolve mode
          • message me on discord @flfff for comments, suggestions, or fun puzzles! alternatively, you may create an issue on the github.
