Actually the missing right parenthesis appears in the equation for 'Den(Calc)' 
a few lines down ;-).

<DIATRIBE>... and if people took the trouble to understand operator priority in 
equations (e.g. multiple/divide before add/subtract otherwise left to right) 
then the superfluous parentheses wouldn't be needed, the equation would be much 
clearer and easier for readers of the Wiki to verify, and mistakes like this 
would be somewhat less likely.</DIATRIBE>
