If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.
52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).
8 [2nd][x/y] 3 [2nd][nPr] gives 336
This took me forever to find out, so hopefully it will help someone!

I had the same problem and finally figured out how to fix it. You need to clear the memory. To do so, first press and release the 2nd button at the top left of the calculator. You will see "2nd" appear on the screen at the lower left. next press the 0 button (which 2nd function is "Reset"). The key to making this work is: do not hold the 2nd button while pressing the 0 button. You have to press it, release it, and then press the 0 button.
