Math Memory Match

This is a car memory game with math puzzles. You don't need to guess anything to find a matching pair of cards. In the board, some cards have arithmetic expressions and others have numbers written on the back. Each number is the result of the given expression. Before clicking on a card, simply solve the expression and find the other card in the deck that has the same number. If both cards have the same value, the card will remain face up; otherwise, you lose a life in the three-card set. Match all the cards in the board to complete the level.
