The Product symbol (∏) is one of the mathematical symbols characters in the AllSymbols catalog. It comes from one of the Unicode Mathematical Operators blocks (U+2200–U+22FF or U+2A00–U+2AFF), which collect the operators, relations, and quantifiers used in mathematics. These characters are designed to align visually with each other and with the rest of math text.
For inline math expressions in body text, captions, and chat, Unicode operators read more cleanly than ASCII substitutes. Use the proper minus sign (−) instead of the hyphen-minus, the multiplication sign (×) instead of the letter x, and the not-equal sign (≠) instead of the != digraph. For typeset math (proofs, papers), prefer a real math typesetting system — Unicode is for plain text.
In Unicode, Product sits at code point U+220F. Web pages reference it with the HTML numeric entity ∏; CSS rules reference it as a quoted hex escape (the four-digit code prefixed with a backslash); in JavaScript and most modern source-code contexts you can either paste the literal character or use a Unicode escape with the same hex digits.
Some math operators have ASCII look-alikes that mean different things: the bullet (•) is not the multiplication dot, the asterisk is not the multiplication sign, and the slash is not the division sign. When precision matters, copy the dedicated character.
If Product isn’t quite what you need, the Mathematical Symbols page lists every related character on the site — including Plus Sign and Integral. The related-symbols grid below also surfaces the closest sibling characters.
