About Flash: Mental Math
Train your mental arithmetic with numbers that flash one at a time. Watch the sequence, add it in your head, and enter the total before the next round. Flash keeps practice simple: • Choose 1–7 digits and 2–500 numbers. • Set the display speed from 0.1 to 3.0 seconds. • Practice 1–999 rounds or keep going in Infinite mode. • Turn answer input and automatic continuation on or off. • Choose a light or blue background. • Use sound, haptic, or both for feedback. • Save your favorite settings as presets. • Check accuracy, response time, streaks, and total training time. • Review the exact number sequence for each round and retry mistakes. Use it for a quick session or a longer challenge. Flash gives you a clear way to practice at your own pace. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
