SUMMARY

In Microsoft Excel 5.0 or 7.0 Help, the definition of the LINEST slope formula is described as the following (in the "Remarks" section in Help):
   m = n-(Sxy)(Sx)(Sy)
       ---------------
       n(S(x2))-(Sx)2
				
The correct definition is the following:
   m = n(Sxy)-(Sx)(Sy)
       --------------
       n(S(x2))-(Sx)2
				
The difference between the two functions is the minus (-) sign after the first "n."

NOTE: The "S" in the formulas represents the Greek symbol sigma, which in scientific notation, means sum or sum of.
