There are 80 student paintings on the walls of a classroom. There is a stack of paintings that need to be put up on the walls, but first, 10 paintings are taken down. If there will be 90 pictures on the walls after the paintings in the stack are put up on the walls, how many paintings were in the stack?

there are 80 already up on the wall. If they take 10 down how many do you have left?
