I put a few maths symbols in the description up top. You should be able to drag your mouse across one, then copy and paste it into the post like this:

√4 = 2

2 ≠ 3

2² = 4

³√(27) = 3

(x) = x³

θ = 20°

Hope this looks and works fine for everyone.

So, ryudo, what are you studying in math at the moment?

I have to go now, but if you reply here, I will see it later and reply to you - so be sure to check back in a day or so.

Bye for now.

That is amazingly useful.

∫3x² dx=x³+c

Sorry, felt like trying it out...

Why did the vector cross the road?

It wanted to be normal.

2 ÷ 1 = 2

½ × 2 = 1

θ = theta (I think)

Oh, no! What does this one mean? ±

√4=±2.

Because 2² and (-2)² both=4

θ is indeed a greek letter called theta, usually used in maths for angles.

Theta drags. Omega is the best greek letter.

I prefer lambda and mu.

We obviously can't forget Pi, Phi and Psi.

Yeah.....why did the greeks have to be so good at math?

I suppose so. I had a Greek maths teacher, and she was really really nice!
