What is a mathematical expression.

An equation is a mathematical statement wherein two expressions are set equal to each other. The structure of defining math expression advances in different grades. Expression is a mathematical phrase which combines numbers variables and operators to show the value of something. A math expression is different from a math equation.

In mathematics an expression or mathematical expression is a finite combination of symbols that is well formed according to rules that depend on the context. All mathematical expressions contain terms and each term has a coefficient the numerical factor. When we combine numbers and variables in a valid way using operations such as addition subtraction multiplication division exponentiation and other operations and functions as yet unlearned the resulting combination of mathematical symbols is called a mathematical expression. A sentence fragment that stands for a single numerical value.

An equation will always use an equivalent operator between two math expressions. Mathematical symbols can designate numbers variables operations functions brackets punctuation and grouping to help determine order of operations and other aspects of logical syntax. In early grades children are expected to write math expressions using numbers and.
