Multiplication Parentheses Notation
Two expressions placed next to eachother and separated by parenthesis are assumed to be multiplied together.
Since multiplication is a very common operation in mathematics, there are alternative, short-hand ways of expressing the operation. In elementary mathematics the times symbol (×) is often used, but then later dropped in favor of the center dot, parentheses, or implicitly represented by two variables next to each other.
A dot between two numbers denotes multiplication in mathematics.
In mathematics when two variables are next to each other the implied operation is multiplication. This makes many equations and formulas more simple.
When entering an expression in a computer multiplication is represented using the asterisk symbol.
Multiplication is a basic arithmetic operation performed on two numbers. Multiplying a number by another number is the same as taking n groups of the other number.
