Clear the display field automatically for new equation input. #13
Description
Standard functionality of calculators -- universally, AFAIK -- allows a new equation to be input after solving the one before it without having to manually clear the field. Upon displaying the answer to equation #1, user can typically just start typing equation #2 and the answer from #1 is automatically cleared upon pressing the first input button.
Obv, this allows for a faster workflow as multiple equations can be solved in rapid succession.
