Answer
The multiplication symbol "×" was introduced by William Oughtred, an English mathematician, in his book "Clavis Mathematicae" published in 1631. Prior to this, various notations such as a dot (⋅), an asterisk (*), or simply the word "times" were used to denote multiplication. Oughtred's symbol gained popularity due to its simplicity and ease of use, and it eventually became the standard symbol for multiplication in most parts of the world.
