> Math is precise.
No, this statement is too strong. There are many examples in mathematics where one cannot exactly calculate a result (e.g. because one doesn't know all inputs), but one can give an estimation and prove that it is good enough for a certain purpose.

- run4yourlives 15y agoCertainly, but in order to properly appreciate these more advanced aspects, you need to have an appreciation of the precision and logic of more basic math. More importantly, I'd suggest that you need to know very basic math (simple addition, subtraction, multiplication and division) on the same level that you can type at your keyboard or drive a stick shift. If you're spending brain effort on the basics, you've got less of it left for the complexities, making the entire exercise much more difficult.
