Equation Not Returning Correct Answer

I have an equation (“RD#@Annotations”*.104) that does not return the correct answer.  By my calculations if “RD#@Annotations” is 561 than the result should be 58.344 (at least according to my calculator and Excel).  The equation editor in SW says it is 56.09375.  Has anyone run into a situation where they get the wrong answer to an equation?
