Is that because you were mostly taught that?

Pretty much. That's what I was taught when I was first introduced to logs, and I've just stuck to it. I don't know which is used most throughout the world though.

Don't worry too much, anyone who knows enough about logs to understand that section will be able to figure out what base you're using pretty quickly.

I usually use log = log(10) and ln = log(e).

Is that because you were mostly taught that? Do you think I will also confuse most people?

(PS: there does seem to be conflicting standards on this!)

]]>So, xy would be order 2 then? That makes sense.

especially if you consider a system of equations such as xy = 2 and y = 2x + 3, substituting you get y = 4/y + 3 which becomes y^2 - 3y - 4 = 0 which is obviously a 2nd degree equation.

]]>I think the loggy limits addition looks good. I was a bit worried that it would be too advanced, but it's explained very well so people could probably follow along anyway. I was confused by your example for a bit before I realised that you were using logs with base e, but that's probably just me. I usually use log = log(10) and ln = log(e).
