Mental Math Chain

Track a running calculation as operations flash one at a time. Combines working memory load with arithmetic processing.

Game Settings

4 operations, +, -, and ×

Watch the starting number and each operation carefully.

Calculate the running total in your head.

Enter your final answer when prompted.

7→+5→×2→24

How to Play

  1. Watch the starting number appear
  2. Operations (+5, ×2, -3, etc.) will flash one at a time
  3. Keep a running total in your head
  4. Enter your final answer when prompted

Difficulty Levels

  • Easy: 3 operations, addition and subtraction only
  • Medium: 4 operations, includes multiplication
  • Hard: 5 operations, all operations including division

Tips

  • Focus on the current total, not individual operations
  • Use the number pad or keyboard to enter your answer
  • Operations are shown briefly - stay focused!

Why It Works

Mental math chains are a dual-task exercise that trains working memory (holding the running total) while simultaneously engaging arithmetic processing. This combination creates an effective cognitive workout.
