I did manage to pass some maths courses in uni, but I don't do arithmetic calculations in the cockpit excepting time and distance with the help of the fancy watch or whiz wheel.
The main reason being that the office is moving at a great rate of knots and I have only one brain that is good for only one thing at a time - - a matter of great dissatifaction with the ex who wanted to discuss deep relationship issues while I was driving at 70+ mph in traffic
The profile view of an approach makes it plain how high I have to be where.
