Creating a form to input numbers using plus sign and negative sign.

Im doing a small project at work. This needs an input form that accepts only (+) plus (-) minus, with a resulting out put of 1 for plus and 0 (zero) for minus.

what I had tried to ask, was I create a form to be used in science project, where results are entered as either positive
or negative. But the out put should generate the 1 for positive and the number 0 (zero) for negative.
Not sure if that tries to explain my reasoning.

Thanks
