# What does sup mean?

I found this formula regarding calories burned:

Rate per Pound (Cal/lb-min)=A+BV+CV.sup.2 +KDV.sup.3 where:

V=Running Speed (mph)--limited to a minimum of 3 mph and a maximum of 14 mph

A=0.0395

B=0.00327

C=0.000455

D=[0.00801(W/154).sup.0.425 ]/W

W=Weight (lbs)

But what do the .sup.2 and .sup.3stand for? What does it mean?

I expect it is meant to indicate that what follows is an exponent. So (W/154).sup.0.425 means $(W/154)^{0.425}$; KDV.sup.3 maans $KDV^3$, etc. –  Arturo Magidin Jun 21 '12 at 21:20

It means superscript (usually an exponent). For example, the first equation is supposed to read: $$\text{Rate per pound (Cal/lb-min)} = A + BV + CV^2 + KDV^3$$
I suppose it means $CV^2$ and $KDV^3$...
