In its most elementary form multiplication is the repeated addition of whole numbers or integers.

The result of a multiplication is the product. The numbers which are multiplied together are called factors.

In this context, it is also one of the most well-known commutative operations: It yields the same result, regardless of placement of numbers.

For example Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 3\times 2 = 2\times 3} .

Multiplication also possesses the associative property.

The opposite of multiplication is division.

Properties of Multiplication

Multiplying any number by 1 yields that same number again. E.g. Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 8\times 1 = 1}
Multiplying any number by 0 yields 0. E.g. Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://wikimedia.org/api/rest_v1/":): {\displaystyle 7\times 0 = 0}

-'''Multiplication''' is a mathematical operation. Multiplication of positive integers is the same as repeated addition.  You multiply two numbers together; that is, multiplication is always performed on two ''operands.'' The result is a third number Multiplication is repeated addition. For example:
+In its most elementary form '''multiplication''' is the repeated [[addition]] of [[whole numbers]] or [[integers]].
-*3 times 2 = 2 added three times = 2 + 2 + 2 =  6.
+:For example, <big><math>3\times 2 = 2 + 2 + 2 = 6</math></big>
-This also works the other way:
-*2 times 3 = 3 added two times = 3 + 3 = 6.
-x 3 = 3 x 2, regardless of the order of the operands. It is said that multiplication is [[commutative]].
-Multiplication is sometimes confusing because the symbol for multiplication is very similar to the letter x; but the letter x can also stand for a variable in algebra, as in "solve for x."

+* Multiplying any number by 1 yields that same number again. E.g. <math>8\times 1 = 1</math>
+* Multiplying any number by 0 yields 0. E.g. <math>7\times 0 = 0</math>
-In printed material, slightly different symbols are used for the letter x and the multiplication symbol &times;. Sometimes, in mathematics, a centered dot is used to stand for multiplication:
-:3 &middot; 2
-:a &middot; b
-:6.022 &middot;10<sup>23</sup>
-In algebra, quantities may simply be juxtaposed (written next to each other) without any symbols, to indicate multiplication. In this expression, 2ab means 2 times ''a'' times ''b''.
-:a<sup>2</sup> + 2ab + b<sup>2</sup>
