# Stepping down from an advanced calculator

by mindheavy
 P: 61 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 $\tau_A=\frac{5kN\cdot.040}{\frac{\pi}{2}\cdot(.04^4)}$ and I want to input this without using parenthesis. What is the order to type this in the calculator with?
