By convention, division and multiplication have equal precedence. By convention, you start at the left.

1/(2x) is not equivalent to (1/2)x
division is not associative, you cannot add parentheses as you can w/ multiplication
1*2*x = (1*2)*x = 1*(2*x) =1(2*x) = 1(2x) = 1*(2x) because multiplication is associative

Bill,
Instead of being stubborn, read the link I provided. Or do you have a problem with the Drexler University mathematics department too?
Read this too:

1/2x lacks clarity is open to interpretation. Period. No self-respecting mathematician would write it out that way.
