===Mathematical Operators block===
{{Main|
The Mathematical Operators block (U+2200–U+22FF) contains characters for mathematical, logical, and set notation.

{{Main|Mathematical Alphanumeric Symbols|l1=Mathematical Alphanumeric Symbols (Unicode block)}}
The Mathematical Alphanumeric Symbols block (U+1D400–U+1D7FF) contains Latin and Greek letters and decimal digits that enable mathematicians to denote different notions with different letter styles.

Line 31 ⟶ 30:
The Letterlike Symbols block (U+2100–U+214F) includes variables. Most alphabetic math symbols are in the Mathematical Alphanumeric Symbols block [[#Mathematical Alphanumeric Symbols block|shown above]].
The math subset of this block is U+2102, U+2107, U+210A–U+2113, U+2115, U+2118–U+211D, U+2124, U+2128–U+2129, U+212C–U+212D, U+212F–U+2131, U+2133

===Geometric Shapes block===
{{Main|
The Geometric Shapes block (U+25A0–U+25FF) contains geometric shape symbols.
Line 63 ⟶ 62:
The Arrows block (U+2190–U+21FF) contains line, curve, and semicircle arrows and arrow-like operators.
