How do calculators and computers do integral and differential calculus?

Question

Digital arithmetic seems straightforward, but how do calculators do calculus? How do calculators find the area between two curves, or calculate the instantaneous rate of change of a function?

Thanks for responding

It’s been too long, but I remember programming my pocket computer to do a Newton Cauchy calculation … on something. I forgot. But there are practical ways to do math and get an actual number. You can’t have more than one unknown, but if you are talking about using actual numbers, it can be done by brute force math.
