I just trudged thru this thread, and it does have some redeeming value - now we know the stiffies who will demand that the eqn. as written, is w/o ambiguity because "
third-grade rules always dictate mathematical syntax! . . .damnit!
"
btw, Dari (you strange old fart) I did plug the eqn in to both my HP calc and into Mathcad (both eqn writers) and both gave 2. --the mult next to the bracket forces priority multiplication in the denominator.
