Using sage 5.0 beta 7:

sage: 1/sqrt(2)
1/2*sqrt(2)

This is mathematically correct when taken to mean (by precedence of 
operators)

(1/2)*sqrt(2)

personally I find it confusing, and many of my students (who don't know the 
first thing 
about precedence orders) took it to mean
1/(2*sqrt(2))
with disastrous consequences.

Is there any design choice involved here that I can override to get 
something like
sqrt(2)/2 
instead?

Cheers,
Javier
