The audience of $\mathsf{Pr} \infty \mathsf{fWiki}$ is very broad. This page lists policies to keep $\mathsf{Pr} \infty \mathsf{fWiki}$ accessible to visitors with less advanced knowledge.


Knowledgeable contributors are sometimes tempted to take all pages to a higher mathematical level. The philosophy is that pages of all levels should coexist, in a connected structure.

We all learned to integrate before we really got to know the meaning of $\d x$ as a differential.

Informal Definitions

See also Help:Definitions and Help:Multiple Definitions

$\mathsf{Pr} \infty \mathsf{fWiki}$ is not Wikipedia, which means that a definition page should be a precise and rigorous definition, without introduction.

Informal Proofs

Generalizations and Special cases of Theorems

As an example, algebraic identities such as Completing the Square are valid in other algebraic structures than real numbers. It is however recommended not to state only the most general result, but also a version that high school students can understand.
