Specific examples of allowable transformations (taken directly from the f95 
standard):

original written form-> allowable form
x+y -> y+x
-x+y -> y-x
x+y+z -> (x+y)+z
a+b-c -> a+(b-c)
x+y+z -> x+(y+z)
x*y+x*z -> x*(y+z)
a/b/c -> a/(b*c)
a/5.0 -> 0.2*a

However, the following transformation is not allowed:
a+(b-c)->(a+b)-c
