I searched the thread but it was only mentioned once:

EXCEL

Seriously you can just input the formula once and calculate it for multiple variables without reentering it into your calculator.

Else I use a TI-84+.

Unless you need complex numbers (possible to a limited degree, but painful with the IM* functions). Or correct statistics. Or an overview of all calculations in a worksheet. There are much better options available for mathematics if you have access to a full-blown PC. Even your average graphing calculator can handle more advanced math.

Excel is a pain to do simple calculator math since you have to wait for the program to launch and then set up your function, where a calculator is usually at hand. But I do agree that it is a powerful tool especially when working with large data sets. I also agree that there are more advanced math programs and those programs will take even longer to set up. So I think you should use the simplest tool possible for the given problem because it will be most efficient.

A beaten up HP12C from 1987. Still the King of the Financial Calculators
