There are 160 tissues inside a tissue box.   If Tucker bought 3 boxes, and used 210 tissues while he was sick with the flu, how many tissues would he have left?
When Tucker buys the tissue boxes, he has a total of 160 x 3 = <<160*3=480>>480 tissues.
When he is sick with the flu and uses some of the tissues, he has 480 - 210 = <<480-210=270>>270 tissues left.
