I kind of agree. I guess I can answer to the first question :
"If you bought four packs of tea: chamomile ($4.60), green ($4.15), black ($3.35) and lemon ($1.80) with a $20 note, how much change would you get?"
but to be honest, it would take me an embarrassing long time to do it, and in the end I could very well have made a mistake.
Don't get me wrong : mental calculus is an awesome skill and it so happens that I have lately been trying to improve in this regard. But the fact that not everybody masters this art should not be a surprise.

- antisthenes 9y agoHah, the tax calculation almost certainly would mean that I would get it wrong! I would have given the plain arithmetic answer.
