> I remember learning about simultaneous quadratic equations about 30 years ago, and kind-of understood them at the time.
I remember doing quadratic equations in maths lessons and thinking they were pointless. A year or so later I started Chemistry A-level and in the textbook were quadratic equations, interestingly because higher level maths at GCSE wasn't a requirement, half of the class didn't have a clue how to deal with them.
Kind of a teacher icon -->
