Casio FX-82LB vs Sharp EL-531GH

The Casio seemed to be the standard-issue class calculator. It was well made with nice round moulded buttons, a steel face-plate, and you could flip the case over using one hand like a flip phone.

But I had the Sharp EL-531GH, which was a better calculator. They were both algebraic, and the sharp handled brackets, and much better order-of-operations logic. I.e. typing 'sin' would then prompt for what you wanted the function to work on, unlike Casios of the time which applied the function to the current value.
