1) 3 x 1/4? I'm being a bit silly but is this 3/4 or 3/12?

How do you add surds, I'm slightly confused!

2) 2 root 2 + root 2? Would that be 2 root + 1?

3) root 2 + root 2?

Thanks. :o)

Hint: this question cannot be solved explicitly with the infomation given above, contrary to the logic of many. (COUGH! jimbo abe lincoln cough cough.) I'm looking instead for an "algebraic formula"; if you solved it right you'll know what i'm talking about.
