Click on the button for whatever function you wan to have happen Then, enter your two numbers and watch ScratchCalc do its magic!
This is a WIP (Work In Progress). I will update it so it can do more more functions based on what people post in the comments 12/22/15: Update! The first one in fact: debugged a bit, specifically, I did some work on the Area of the circle button so now it doesn't randomly fire off. Will continue to fix it as it is the most buggy button
