Do you need even more practice with subtraction? This math memory matching game is all about subtracting multiples of ten. Match each question with its answer in the grid. All matches that you may find will earn you a point—find enough matches and you will set a high score! But be warned: you have to move quickly! You only have until the timer at the top of the screen runs out to find as many matches as you can. After the timer expires, the game will end. Use this game as a way to both keep your memory sharp and practice subtraction.
