In mathematics, the sign of a real number is its property of being either positive, negative, or 0. Depending on local conventions, zero may be considered as having its own unique sign, having no sign, or having both positive and negative sign.

In mathematics, the word sign refers to the property of being positive or negative. Every real number that is non-zero is either positive or negative, and therefore has a sign. Zero itself is without a sign, or signless.

In mathematics, the sign function or signum function (from signum, Latin for "sign") is a function that has the value −1, +1 or 0 according to whether the sign of a given real number is positive or negative, or the given number is itself zero.

The list below has some of the most common symbols in mathematics. However, these symbols can have other meanings in different contexts other than math. [source?]

A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.

Math symbols are concise marks, signs, or notations representing mathematical operations, quantities, relations, and functions. These symbols help to represent mathematical concepts and equations concisely.
