Click space to set to a number you want, click the left arrow key to put in a number to go to counting by ones and click right arrow key to start it. If you click z it will set the score to zero, and if you click y, it will reset the animation to zero. The up arrow will make the counter go up by one and the down arrow will make the counter go down by one. A will keep making the number go down by one every second until it reaches zero. B will do the same thing but wait 0.25 seconds instead of one. C is like the animation but going down until it reaches zero. V will add to the counter from your answer, B will subtract your number from the counter, N will multiply the number , and M will divide the number while H will multiply the number by two. The counter will let you go below zero but there will be a "B" instead of a "-". And click P to set the size.
