## Main Question or Discussion Point

This is kind of sad, but I'm beginning to realize how much I rely on my graphing calculator any more for solving equations and whatnot. I am trying to incorporate a much simpler calculator from time to time (CASIO fx-260) and am struggling with some very basic operations.

Say I have the equation [itex]\tau_A=\frac{5kN\cdot.040}{\frac{\pi}{2}\cdot(.04^4)}[/itex] and I want to input this without using parenthesis. What is the order to type this in the calculator with?
