Instead of pushing a button to calculate the area, it would be better if the triangle program automatically calculated the area and printed the results below the input boxes every time it finds a triangle solution. It's too much work to call a triangle area function.

Actually, I would like to see the instructions on the first line say something like "Enter 3 out of 6
values and clear the unknowns", and for the "Help" to say that the unknown values must be cleared and not just zeroed.
