T-SQL math help

one table, 2 columns. columnA has either "rtnsup" or "invsup" as the values,  columnB has amounts.

i can do select sum(columnB) as Total to get a total.

what i need is to total up columnB where columnA is invsup, total up columnB where columnA is rtnsup, and then take total of rtnsup from total of invsup.
