What does {} mean on this calculator? I entered an equation in the calculator sand got this in return. Originally, I thought it meant none, but then I solved the equation manually, and it would seem not. Any help would be greatly appreciated, for I am somewhat flummoxed.

Post what you entered in the calculator, or just post the question, then it will be easer to know what the input error is.
