Sure they do work, and they work exactly the same way. That is acually the
point: currently 1/2 * m * v**2 is not the same as (m/2) * v**2 (in sympy, that
is), with my proposal it would be exactly the same (again, from my prototype,
not fake):
>>> m, v, r = symbols("m v r")
>>> 1/2 * m * v**2
m*v**2/2
>>> (m/2) * v**2
m*v**2/2
>>> (m * v**2) / 2
m*v**2/2
>>> 4/3 * pi * r**3
4*pi*r**3/3
Cheers
Martin
