Math Symbols
Operators, relations, set notation and Greek letters used in maths.
Where these characters come from
Mathematical operators and relations were among the earliest non-Latin additions to Unicode, driven by the need to typeset formulas in plain text. Greek letters are included because they carry conventional meanings in mathematics and physics.
How reliably they render
Basic operators are universally available. Specialised set-theory and logic symbols are well supported on desktop and patchier on mobile.
Questions
Can I use these in plain text instead of an equation editor?
For simple expressions, yes — that is exactly what they were encoded for. Anything involving fractions, matrices or stacked limits needs real layout, because Unicode gives you characters but not two-dimensional positioning.
Why are Greek letters in a maths set?
Because they carry conventional meanings in mathematics and physics. Pi, sigma and delta are used as operators and constants rather than as letters of a language in this context.
