### Relationship between pKa and pKb

If pKa + pKb = pKw = 14, why is it that increasing the pKa also increases the pKb?

I don't know where you heard that but I thought that when the pKa increases that means the pKb must decrease. If together they equal 14, then if one increases the other decreases.

Why would a low value of pKb mean that the base is stronger then?
