Thanks mate, I get some of what you are saying. What throws me is the (f). I don't know where that comes into the equation. Also, I don't know what properties 'log' has. E.g. if someone says what's 2+2 I know to add 2 on to 2, if someone says 2 log 2 I don't know what to do.

There's always the possibility I'm just out of my depth here. Like I said before I don't know any functions like trig etc. All I can do is mental arithmetic like multiplications, divisions, percentages etc.

If you can't be bothered then fair enough, but any chance of 'spelling out' how one of the table results comes to fruition. E.g. '1000 | +60'.

How can a ratio be defined as '1000'? All I know is 2:3 style of ratios.

What does 'log' do to that '1000' number?

Cheers
