Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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?

### Response:
When Tucker buys the tissue boxes, the total number of tissues inside the boxes is 160 x 3 = <<160*3=480>>480.
When he is sick with the flu and uses some of the tissues, he uses 210,, so the total number of tissues left is 480 - 210 = 270.
#### 270
