Numbers are an abstraction. They in no way fit reality.
Numbers (and mathematical operations) help us to understand the world, how stuff relates to other stuff, how stuff works, etc. The modern world and all modern technology is built on understanding derived from numbers and mathematics.
People have used very little math on the things around them. Most of the time, people just live. There is no math in anything until people want to discuss things with each other... and maybe not then.
