In the sonic powerpoint there are a few formulas for weight distribution I don't quite understand...

Number Average ,
Weighted average = ,
Molecular weight average .

Can someone explain what they are for?

number average is doesn't take into account that heavier molecules contribute more to the molecular weight than lighter molecules where as weighted average does.
