Yes? No? Any!

a) 1 is not equal to 2
b) 1 is different from 2

These simple prepositions shows there are at least two ways of expressing things in any circumstances, even in programming.

Sometimes there is no clear way to solve a problem... and I think it is because this essential duality every proposition has.

The normal statement about ways to solve problems is this: "If it solves the problem, then it is good enough."

But in my own personal context, it is important if every proposition can be: maintainable, flexible, extensible, re-usable.

"Math is an specific domain or context, and there are universal truths inside itself."
