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

### Instruction:
 Steve has 25 socks. He has 4 pairs of socks that match, and all the others don't match. How many mismatching socks does Steve have altogether?


### Response:
 Steve a 25 chaussettes.
Steve a 4 paires de chaussettes qui se correspondent, ce qui signifie qu'il a 4 * 2 = <<4*2=8>>8 paires de chaussettes qui se correspondent.
Cela signifie qu'il a 25 - 8 = <<25-8=17>>17 chaussettes qui ne se correspondent pas.
