This game is for practicing the four basic Math operations: addition, subtraction, multiplication, and division. It is to help elementary and middle students (depending on the operation and difficulty) practice their mental math skills. People of all ages (even outside of school) may enjoy tuning up their mental math skills.

MATHPRAT Difficulty.png

Enter a difficulty to play. Note: Difficulty is cumulative, so you may get an easy game, even if you select "15" difficulty. Difficulty is essentially the upper limit of the numbers which may chosen. For example, a difficulty of "15" choses numbers from 0 to 15. You may however get 15/3 which is easy. Note that division is harder than multiplication regardless of difficulty.

Difficulty # Difficulty
6 Easy
10 Medium
15 Hard
40 Impossible
100 Mental Math Champion

Allow Negatives

Enter "1" to allow answers to be negative. If you enter "0" the game will disregard any problems which result in negative answers.


MATHPRAT Operation.png

Standard Info


  • A TI-83 Plus, TI-83 Plus Silver Edition, TI-84 Plus, or TI-84 Plus Silver Edition (Not tested on other versions)
  • A cable to connect your calculator to your computer.
  • The software to make your computer talk to your calculator. (It should have come with your calculator or cable)
  • Free space on your calculator.
    • 16,384 blocks for APPS
    • 303 blocks RAM for SNAME PRGM
    • ~100 blocks RAM for simple PRGMs
    • ~500-1000 blocks RAM for complicated PRGMs like games


The TI GraphLink cable and TI-Connect software
  1. Have installed TI-Connect (the software which came with the cable/calculator)
  2. Download the PRGM "SNAME" which is required to be on your calculator for all PRGMs. APPs like "FERRIS", don't need SNAME.
  3. Download the PRGM (.8xp) or APP (.8xk) file to your computer. Save it somewhere.
  4. After downloading, find it on your computer. Right click and hit "Send to TI-Device"
  5. TI-Connect will open. Choose your calculator and wait for it to transfer. Make sure you have enough free space on your calculator.


Go to [PRGM] scroll to the program's name. Push [Enter] to select it and then [Enter] again to run it. You will see a splash screen. Hit [Enter] to continue.


To exit the program, hit [On] key and push [Enter] or [1] to quit.


To delete a PRGM or APP, push [2nd] [MEM] [2]. Then push [7] for a PRGM or [ALPHA] [A] for an APP. Find the one you want to delete and hit [DEL] [2].

Error: Memory?

If you are getting the error when you want to run an APP, you don't have enough free RAM memory. You need to archive a PRGM. Do this by hitting [2nd] [MEM] [2] [7], finding the PRGM you want the archive, and hit [Enter]. Note you need to unarchive it before you can run it again (Unless you use Mirage or similar OS to run archive PRGMs.)


Note the program might set your calculator in degrees mode, change the graph settings, turn off floating (rounding), and/or overwrite variables. After running the program, make sure your calculator is back the way you want it before doing other things.
