@MarshaBradyo couldn't agree more! My lad did maths, economics, etc. just qualified as a chartered accountant. He wouldn't have needed extra maths.
However, he could visit and give them a chat about the delights of using a spreadsheet to organise every element of your life! 
I was an oxford undergraduate. Very bright. Good education. I didn't recognise my first trip 'into the red' in my bank statement. It wasn't in red, and there were no negative numbers. Just a D after the figure instead of a C.
It's pretty basic, but my excellent education didn't cover it.
