Description mathematical formula representing the definition of a mathematical concept Mathematical expression instances and subclasses of mathematical concept (Q24034552) absolute value (Q120812) → ${\displaystyle \left\{{\begin{array}{rl}x,&{\text{if }}x\geq 0\\-x,&{\text{if }}x<0.\end{array}}\right.}$ absolute value (Q120812) → ${\displaystyle x\mathop {sgn} (x)}$ defining formula (P2534)

#### Motivation

defining formula (P2534) allows to add the formula that defines a mathematical statement, but currently there isn't a property to add the formula that defines a mathematical concept. Malore (talk) 18:00, 10 June 2018 (UTC)

#### Discussion

•   Support David (talk) 16:21, 14 June 2018 (UTC)
•   Oppose per Arthur, just use defining formula (P2534) - feel free to broaden its description and usage instructions to reflect that. − Pintoch (talk) 13:50, 15 June 2018 (UTC)
