About PEMDAS App

PEMDAS is a simple but powerful desktop calculation app that lets you work with equations and variables.

Stay tuned—updates are coming in 2014.



The most important feature of PEMDAS is working with equations. Simply type in an equation, hit enter, and you have the answer! Above the entry field is the equation history, where PEMDAS displays all your previous calculations.

Variable List

On the side of the application is the variable list. This lets you easily see all of the variables active in the current document.

Number Formatting

PEMDAS has several different kinds of number formatting, including float, scientific, and engineering. It also lets you specify the number of decimals or significant figures to display, and lets you add thousands separators.
