ActionScript help

[~J~]

Any ActionScript users out there?

Can someone explain what calculations are done on the following please:

rs += pwr*varc/2;
varc *= friction;
vard -= pwr;

Does rs = rs + pwr * varc /2
or is it rs + (pwr * varc/2)
or is it rs + (pwr * (varc/2))

varc, is that varc * friction?

and vard, is that vard - pwr?

Thanks for that.
