Flash-Fast Math

Practice makes perfect! As with anything, if you practice math, you will improve. This app shows you a screen with a quick-math arithmetic problem on it, and it asks you to answer if the shown number is correct or not. If it is correct, tap on a green checkmark. Otherwise, tap the red "X".

This is similar to many of the apps already available, but without any ads. In addition, this app lets you choose how long it lets you think before the game is over. Available time durations are between 1 and 9 seconds as of this version. There are number pickers for these durations on the "pause" / "game over" screen.

Similar to some of the other apps, answering incorrectly takes you to the "game over" screen as well.
