What is preventing you from living peacefully?

This isn't nonsense. It's actually true. I find it hard to understand such an approach: "Here's a formula, and like a sheep, follow it exactly, don't deviate, only follow the rule... and only use precise numbers." Personally, this bothers me. In geometry and physics, there are also rules and formulas, but there's room for thought. In algebra, however, one step off, and everything is wrong.
