Enter a number by clicking on the number key pad on screen. Next choose an operation such as +, -, X, or /. Next enter the second number. Finally, click = to get the result. Press C to start over.
This is the first version of a very simple calculator that takes two numbers and performs simple math operation on them. It was created from scratch, pun intended, without looking at other projects. I know there are more fancy calculators out there. Just wanted to see how to build on with nothing to based on.
