I am in need of a simple calculator app for my Blackberry device. It will be coded in java and be delivered as a .jad file that I can then install onto the device. I want to be able to enter an equation in free-hand. Example: 7*7+21, followed by Enter. I want the result to pop-up. I have a specific reason for needing this designed in this way. It will be strictly for personal use. Please ask any questions.
