The language of physics is mathematics. In order to study physics seriously, one needs to learn mathematics that took generations of brilliant people centuries to work out. Algebra, for example, was cutting-edge mathematics when it was being developed in Baghdad in the 9th century. But today it's just the first step along the journey.
The entire game is pretty much all math when you think about it. Newtonian physics are heavily simulated in KSP. Without the use of math in KSP, the game wouldn't be able to do much. Your rocket wouldn't be able to get off the ground and out of the atmosphere into space.
