Si darling,
Go and do your maths homework like I told you!
SQRT 4 = 2
SQRT 1 = 1
SQRT 0.5 = 0.7
SQRT 0.1 = 0.3
SQRT 0.01 = 0.1
SQRT 0.001 = 0.03
Diddly-squat is a small but finite and positive number!
See me after class!
Cheers

To all the pedants out there (and I know who you are!), I have done these to one significant place 'cos I CBFA to type in the rest of the numbers. I'm an accountant, not a scientist any more!
