# 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:
 commutative-rings× 176 descriptive-set-theory× 175 projective-geometry× 175 teaching× 175 For questions related to teaching mathematics. For questions in Mathematics Education as a scientific discipline there is also the tag mathematics-education. manifolds× 169 approximation-theory× 168 stable-homotopy× 165 computational-geometry× 164 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× 162 birational-geometry× 161 algebraic-surfaces× 159 hilbert-spaces× 151 random-walk× 151 riemann-zeta-function× 151 the function of one complex variable $s$ defined by the series $\zeta(s) = \sum_{n \geq 1} \frac{1}{n^s}$ when $\operatorname{Re}(s)>1$.
