With addition and subtraction, you can do every other mathematical function. 5*100 is just adding 5, 100 times. But it’s faster if you add two zeroes after 5. Doing that sort of thing takes specialized “optimized” hardware which changes a processor.
GPUs have more physical hardware for matrix math operations like rotating and translating matrices, which is what we use to describe 3D points in space, which are used to display graphics.
