Math Attack

This is a memory match game with an additional difficulty on it because you are not only matching two cards based on their face, you are matching them based on their face value! To play this game, after you click on the play button you will see several cards facing down. Click on any one card and it will be flipped face up. The face of the card may contain number or it may contain mathematical formula. If the face contain a mathematical formula, count the result quickly and memorize the result rather than the formula. Click on any other card and it will also be flipped face up. Like the first card, if the face contains mathematical formula, memorize the result rather than the formula. Once you click on that second card, you have about 1 second before both cards flipped back face down so you have to be quick. Based on what you memorize, you have to find another card with face that contains the same value. When you click two cards with the same face value, they will be removed. There is a timer on the bottom right of the game screen, which tells you how many seconds you have left to remove all cards from the screen. If the timer runs out before you are done, it is over.
