Order of operations
Authored by: Baggins on May 25, '05 11:48:40AM

No, order of operations was not determined arbitrarily. It has to do with getting accurate answers. Since multiplication is repeated addition, it MUST be done before simple addition or you will get an incorrect answer and your bridge will collapse, your engine explode, etc.

The same is true with exponents, logs, differentials, etc. They are evaluated in a certain order because they HAVE to be in order to give the correct answer.
