I've used HP calculators most of my 30+ year engineering career and recently got a TI-30XIIS. I made the following notes to remember the different ways operators accept their parameters and thought it might be helpful to others. If pressed after a calculation result some operators automatically act on Ans and are marked with * to the right. All others require the ANS key to act on the previous answer. Corrections and/or additions are welcome.

Code:
2 parameter midfix: + - * / ^ <xth root> % nPr nCr 9*
2 parameter prefix: R->Pr R->P<theta> P->Rx P->Ry RANDI 5
1 parameter prefix: LOG 10^x LN e^x sqrt 5
SIN COS TAN ASIN ACOS ATAN [+6 HYPs] 12
1 parameter postfix: x^2 x^-1 ! ->DMS F<>D Ab/c<>d/c 6*
0 parameter: RAND 1
