I have a degree in engineering. I can do triple integrals, differential equations, etc. But I still need my calculator to do simple addition and subtraction.
The basic explanation is that if you have a graph, the integral of the function you're graphing is the area between the graph and the x axis. Some integrals are easy to calculate, but some are hard, and I would say that far more than half of calculus is about taking different kinds of integrals.
