Math Symbols
Click any symbol to copy it. 20 characters, each labelled with its Unicode code point.
Most of these are genuine operators from the Mathematical Operators block, which means they carry semantic weight: software that parses mathematics will treat them as operations, not decoration. This collection holds 20 math symbols drawn from 2 Unicode blocks — mainly Mathematical Operators and Latin-1 Supplement. Code points run from U+00B1 to U+2265. All of them sit in the Basic Multilingual Plane, which means broad font support and very few encoding surprises.
Operators, not lookalikes
× (U+00D7) and ÷ (U+00F7) are real multiplication and division signs, not the letter x and a colon-dash. Using the correct characters matters if the text will ever be read by software, copied into a formula tool, or spoken aloud.
The large operators
∑ ∏ ∫ are display operators. In proper mathematical typesetting they change size with their context; as plain Unicode characters they stay one fixed size, which is why they look small next to a tall expression.
Greek letters are encoded twice
∆ (U+2206 INCREMENT) and Δ (U+0394 GREEK CAPITAL DELTA) look the same and mean different things. Mathematics also has a full set of styled alphabets in the Mathematical Alphanumeric Symbols block, separate from the Greek block.

Frequently asked questions
Should I use × or the letter x for multiplication?
Use × (U+00D7). The letter x is a letter: it sorts, searches and is announced as one. In running text the distinction rarely shows, but in anything parsed or read aloud it matters.
