Calculating combinations and permutations on a TI-36 Solar Calculator?

Click For Summary
SUMMARY

The Texas Instruments TI-36 Solar calculator includes functions for calculating combinations and permutations. To compute combinations, such as C(5,3), users should follow these steps: press 5, then 'a', followed by 3, 'b', then '2nd', and finally 'nCr'. For permutations, the process is identical, except 'nPr' is used instead of 'nCr' at the last step. This functionality is confirmed to work effectively on both new and older models of the TI-36.

PREREQUISITES
  • Understanding of basic combinatorial mathematics (combinations and permutations)
  • Familiarity with the Texas Instruments TI-36 Solar calculator
  • Knowledge of calculator function keys (e.g., '2nd', 'a', 'b')
  • Ability to follow sequential instructions for calculator operations
NEXT STEPS
  • Research the mathematical principles behind combinations and permutations
  • Explore advanced functions of the TI-36 Solar calculator
  • Learn about other Texas Instruments calculators and their functionalities
  • Investigate practical applications of combinations and permutations in real-world scenarios
USEFUL FOR

Students, educators, and anyone interested in using the TI-36 Solar calculator for mathematical calculations involving combinations and permutations.

My mom has a Texas Instruments TI-36 Solar calculator. A few days ago I found that there are functions for calculating combinations and permutations. The trouble is I can't seem to figure out how to use them.

I have an old TI-36 myself (still working great after many years). To calculate C(5,3):

1. Press 5
2. Press a
3. Press 3
4. Press b
5. Press 2nd
6. Press nCr

Permutations are similar, but press nPr at step 6.

Hey, thanks!

If there are an infinite number of natural numbers, and an infinite number of fractions in between any two natural numbers, and an infinite number of fractions in between any two of those fractions, and an infinite number of fractions in between any two of those fractions, and an infinite number of fractions in between any two of those fractions, and... then that must mean that there are not only infinite infinities, but an infinite number of those infinities. and an infinite number of those...
