@garyackerman Yes, I think calculators have shifted from being a 'calculation' device to an 'algebraic evaluator'. One was for calculating, the other is trying to be a mathematician (and often doing it wrong too).
@garyackerman
Except most calc apps have been written by programmers who didn't even know basic order of operations rules (the Windows calculator in Standard mode says 2+3x4=20), so unless you have a hand-held calc (and not a Texas Instruments one) you're still on your own!
