Make it all add up!
Form Calculator takes the form fields on your page and creates a mathmatical equasion to solve your form calculation problems. Handles textfields, checkboxes, hidden fields and select fields for calculations. Does addition, subtraction, multiplication and division and uses parantheses to control order of calculations. Validates the math equasion and allows manual entries. You can edit your prior instances and you can set the rounding for 0 (integers) to 10 places.
"Obvious" is the most dangerous word in mathematics.
