U+00D7 × MULTIPLICATION SIGN. The division sign ( ÷) is a mathematical symbol consisting of a short horizontal line with a dot above and another dot below, used in Anglophone countries to indicate the operation of division. This usage, though widespread in some countries, is not universal and the symbol has a different meaning in other countries.
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [ 2][ 3]

In mathematics, the symbol × has a number of uses, including. Multiplication of two numbers, where it is read as "times" or "multiplied by" [ 1] Cross product of two vectors, where it is usually read as "cross". Cartesian product of two sets, where it is usually read as "cross" [ 6] Geometric dimension of an object, such as noting that a room ...
propositional logic, Boolean algebra, first-order logic. ⊥ {\displaystyle \bot } denotes a proposition that is always false. The symbol ⊥ may also refer to perpendicular lines. The proposition. ⊥ ∧ P {\displaystyle \bot \wedge P} is always false since at least one of the two is unconditionally false. ∀.
Glossary of mathematical symbols. 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. As formulas are entirely constituted with symbols of various ...
Quadratic formula. The roots of the quadratic function y = 1 2 x2 − 3x + 5 2 are the places where the graph intersects the x -axis, the values x = 1 and x = 5. They can be found via the quadratic formula. In elementary algebra, the quadratic formula is a closed-form expression describing the solutions of a quadratic equation.
Fundamental symbol. The integral symbol is U+222B ∫ INTEGRAL in Unicode [ 5] and \int in LaTeX. In HTML, it is written as ∫ ( hexadecimal ), ∫ ( decimal) and ∫ ( named entity ). The original IBM PC code page 437 character set included a couple of characters ⌠ and ⌡ (codes 244 and 245 respectively) to build the integral ...
