I think people should master arithmetic, but once they've done that, it's silly to do it by hand except when you have to.I always find myself going right to my phone calculator. My job has a lot to do with money fraud and laundering, so I'm always having to crunch the numbers.
School taught me that - using a calculator.
Imagine if I just got to use a pencil and paper though. I bet I'd be just as fast with it and also utilizing more of my brain.
