@@scottcollins7513 The Prime is a Windows GUI math app masquerading as a calculator on a small screen . There is no reason for a calculator to have a drop down menu with multiple layers to call a function.

Even though I have traditionally preferred CASIO (and even SHARP), I like the TI best for this type of calculator. But, if your only option is the TI-36X Pro, it is less compelling b/c it is just an old design. 2 - Would you prefer the benefit fewer keystrokes to get to the answer at the cost of being less user-friendly? Or, do you like the benefit of user-friendly at the cost of things taking more keystrokes to answer? My personal GENERAL preference would be: 1st - TI-30X Pro MathPrint 2nd - CASIO fx-115ES PLUS 2nd Edition 3rd - CASIO fx-991EX 4th - TI-36X Pro My personal PRECALC-specific preference would be: 1st - TI-30X Pro MathPrint 2nd - CASIO fx-991EX 3rd - CASIO fx-991CW 4th - CASIO fx-115ES PLUS 2nd Edition
