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.
awkward said: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.
