Another Newbie.. But fairly old.

Hi. I am certainly no mathematician, I am an Electronics Tech/Eng of 50 + and spent most of my working life avoiding any serious maths and just making things work. However I seem to have moved on to the teaching/instructing sphere and my maths is very rusty so I was looking through the posts here and finding answers, thankyou all. I now realise I never understood Calculus even when I left college and just really did it all rote? I still am not sure of it as it looks like alot of div by zero errors! Anyway keep up the good work and apologise in advance for being a taker and not a giver, but if you need something electronic fixing I am sure I could help :)
