### Instruction:
Anna has 50 pencils and Harry has twice the number of Anna’s Pencils but he lost 19 of them. How many pencils are left with Harry?

### Response:
Anna has 50 pencils
Harry has twice the number of Anna’s Pencils so he has 50 * 2 = <<50*2=100>>100 pencils
However, Harry lost 19 of them then he is left with 100 – 19 = <<100-19=81>>81 pencils
