Well, I'm well aware of DSOrganize's calculator, but it doesn't work the way I want to. Because, I have a scientific calculator ( A $14 one! Best darn calculator I've ever had) and I love how you can use the parenthesese. As opposed to basic calculators that only can handle one function at time. What I'm trying to say is, I would like to be able to input an equation that goes like this: 27 - (27 * .3)/3 On a scientific calculator, you get the answer in one swift motion. But, on a regular calculator, you're going to be going through numerous steps. I saw parentheses in DSOrganize, and attempted to use it, but I got a basic calculator function. Is there any homebrew out there that can do what I need?
