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

### Instruction:
 Autumn was constantly misplacing her pencils. At the start of the school year, she purchased a pack of 20 pencils. In the first month of school, she misplaced 7 pencils, broke 3 pencils and had to throw them away, she found 4, and bought 2. How many pencils did Autumn have left?


### Response:
 Autumn avait 20 crayons au début, puis elle en a perdu 7, cassé 3, retrouvé 4 et acheté 2 de plus.
Elle lui restait donc 20 - 7 + 4 + 2 = <<20-7+4+2=19>>19 crayons.
