Can someone explain to me, in plain english whats going on in this line

```
hourly_wage = int(input('Enter hourly wage: '))

```

From what I understand integers allow you to multiply,add and divide. If I were to say fruit = apples + 10
and I didn't have an integer function to call that out there would be an error.

I am just trying to grasp the next step of that. I may be wrong in the above explanation, if I am please correct me. Thank you for your help.
