Sigma icon

Sigma is one of the math icons in Majesticons, drawn by hand on the library's consistent 24×24 grid. All 3 styles (line, duotone and solid) stay visually consistent, so it slots cleanly into calculators, spreadsheets and formula editors.

It pairs naturally with the minus box and minus circle icons from the same collection. Browsing is free; a one-time Majesticons license unlocks SVG copy and download for the entire library.
