Have you done a mystery word puzzle before? This game is based on the same idea, except you have to look for mathematical operations and not words!
To play this 2-player game you need a grid filled with numbers. In turn, each player looks for three consecutive numbers which form a mathematical operation. Find sums and differences, horizontally or vertically, from left to right or right to left. The goal is to find as many operations as possible. Have fun!
