New Game Idea
Iโve been playing around with the TI-84 calculators for a while now, and I have some challenges for anyone who is brave enough.
Rules:
1. Give a numerical answer. All calculations must be done on the TI-84. If a number is too large or a decimal, numbers rounded to 8 or more decimal places is OK.
2. No programs must be written. No Python, no prgm programs, no apps, just every native function.
3. Assume the RAM has been cleared.
3. Brute force is possible, but not recommended. To combat this, every challenge has the number of presses I took from a cleared RAM. Try to match it, or do better!
If you donโt have a TI-84, you can play along here.
Here are my current favorite challenges:
1. What is 20! ? (par: 7)
2. What is the sum of the reciprocals of 1-100? (par: 12)
3. Get a syntax error in 2 presses
Get a domain error in 3 presses
Get an overflow error in 6 presses (unsolved: 5 might be possible)
4 (HARD). Find the 250th Fibonacci number (par: 24)
5 (BONUS). Get your calculator to display โ15โ using 1 key press.
