1. The problem statement, all variables and given/known data

I recently came across a simple type of integral that I did not know how to evaluate. Generally speaking how would one interpet $$\int_0^a dxf(x)$$?

2. Relevant equations

3. The attempt at a solution
At a glance, I thought to integrate with respect to 1, but then noticed the f(x) touching the differential. I have never seen this before.

That's just a different way of writing

$$\int_0^a f(x)dx$$

I feel like an idiot. Thank you very much.
