Please define what the "operators" are. Also, are spaces allowed in the middle of the value? – Tim Biegeleisen May 13 '22 at 06:44

Operators are +,-,/,* – Simran Kumari May 13 '22 at 06:46

can operators be next to each other? e.g. `123+/3` - can their be a trailing operator? `123*` ... can there be a leading operator `/123` ... is `-` a valid leading operator? – Bravo May 13 '22 at 06:46

yes It can be anything – Simran Kumari May 13 '22 at 06:48

so you want `/[\da-z+*/-]+/` - correction `/^[\da-z+*\/-][\s\da-z+*\/-]*$/i` - assuming spaces allowed after first character – Bravo May 13 '22 at 06:49

Use: `str.match(/^[A-Za-z0-9\/*+-]+$/)` – Tim Biegeleisen May 13 '22 at 06:50
