Has math changed a lot over the course of nearly 150 years?

Yes. 150 years ago differentiation involved geometry, but today it is different.

What do you mean? Differential geometry is a thing

In the past, math had much more focus on arithmetic skill and speed. It was important for an adult to be able to quickly add, multiply, and divide large numbers in their head. Memorizing times tables was considered vital.

Modern math doesn't really care about that since we have calculators. It's more important to know functions, axioms, and manipulations.

I don't know about 150 years, but I have an engineering textbook from the 20s covering multivariable calc, ODEs, PDEs, and statistics, and everything is exactly the same as we learn today, except they discuss numerical approximation methods that are obsolete due to computers.

No, the derivative of a function used to be calculated geometrically. See: https://www.youtube.com/watch?v=ObPg3ki9GOI&t=115s (1:55)
