Math Memory Match

This is a car-themed memory game that involves mathematics puzzles. You are not required to guess the matching pair of revealed cards. On the board, some of the cards have an arithmetic expression, and the others have a number written on the reverse side. Each number is the outcome of the provided expression. Before clicking on a card, solve the equation and search for the other card in the deck which holds the same number. If both cards have the same value, they will stay open, otherwise, you will lose one of the three lives. Match all the cards on the board to complete the level.
