Funnily all my college math professors and their TAs were notoriously bad at arithmetic. They regularly joked that arithmetic isn’t real math so not a big deal.
My physics professor was an arithmetic magician though. The way he could take a ridiculously complex equation covering the whole blackboard and guesstimate the solution in his head was a marvel to behold.

You can have either calculus or arithmetic in your head. But, it sounds like it's good to have arithmetic in your head before you replace it with calculus.
