The multiplication sign or times sign is the symbol ×. The symbol is similar to the lowercase letter x but is a more symmetric saltire, and has different uses. It is also known as St. Andrew's Cross and dimension sign.

An obelus (symbol: ÷, plural: obeluses or obeli) is a symbol consisting of a short horizontal line with a dot above and below. It is mainly used to represent the mathematical operation of division. It is therefore commonly called the division sign. Division may also be indicated by a horizontal line (fraction bar), or a slash.
