# Tags

A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.

 Type to find tags:
 characteristic-p× 181 teaching× 180 For questions related to teaching mathematics. For questions in Mathematics Education as a scientific discipline there is also the tag mathematics-education. hodge-theory× 179 approximation-theory× 177 birational-geometry× 175 stable-homotopy× 173 algebraic-surfaces× 170 manifolds× 170 computational-geometry× 169 Using computers to solve geometric problems. Questions with this tag should typically have at least one other tag indicating what sort of geometry is involved, such as ag.algebraic-geometry or mg.metr… math-philosophy× 165 riemann-zeta-function× 161 the function of one complex variable $s$ defined by the series $\zeta(s) = \sum_{n \geq 1} \frac{1}{n^s}$ when $\operatorname{Re}(s)>1$.
