I haven't actually learnt anything about the term 'i' in class, but I know how to simplify surds, and that i = √(-1), so can you tell me if i've got the right idea with these?

Both fully correct.
Bad speling makes me [sic]

Hmmm seems pretty simple, is that all there is to know about 'i'?

For practice, check out my exercise on simplifying i terms.

Goodness gracious me no. There's still a ton of fun and exciting stuff to learn about.
Both of the things you had there were imaginary numbers. When you start working with reals and imaginaries put together to get complex numbers, that's when it starts getting really fun. And then you've got the modulus-argument form of complex numbers and all kinds of other wonderfully interesting things. So don't think that complex numbers are just about surd manipulation.
Why did the vector cross the road?
It wanted to be normal.

I hope to start some pages on complex numbers one day.
Going from Real to Complex is like going from the Number Line to Cartesian Coordinates. Almost exactly like that really.
So, you have just popped your head up from the number line along the y axis. Now you need to go explore.
