I get that, but it doesn't explain why there is difference between "two square roots" and "the square root" appart from convention - is there a mathamatical difference.

Sorry still dont get it - the mathamatical notation seems to just be rewriting the previous MOD version in another way.
besides if I solve the problem to find the intersect of the two lines y=5 and y=x^2 I expect two answers although I would represent the solution as [root symbol]5=x. Your argument suggests that the answer is only the positive values.
