After studying GCSE and A-Levels I had never come across those words before studying for my ATPL.
Its a funny upside down old world. I don't have any maths qualifications (In fact I don't have any qualficiations worth speaking of - now how scary is that?) and yet I was quite familiar with these terms and indeed with all the maths in the ATPL syllabus. I suspect you probably did but filed that information in the circular filing bin in your head marked "useless for everyday things."
