YOU DON"T NEED TO PRESS THE GREEN FLAG FOR THE ANSWER! Change a, b, and c and then press the green flag for the values of x for the a, b, and c values. The solver will not work if a is zero. Follows a(squared)+b(x)+c=0 or (negative b + or - (Square root of (b(squared) - 4ac)))/2a=x. If the first thing you do is click the add 1 to a or the subtract 1 from a, one of the x's will be -0. That's what I'd call a glitch.
