This game is found in the art of problem solving prealgebra books. All credit goes to them for making this game! I don't have some of the mathematical symbols on my keyboard, so here is the key: +: Plus -:Minus x:Times ~:Divided by ():Parentheses To ensure you get the right answer remember to put parentheses where you need them! I only have 3 puzzles, still that should keep you entertained for at least a half an hour or more unless you are some kind of math legend! NOTE: you do not have to put in =24 afterwards, so yeah...
