What Is A Mathematical Expression

The structure of defining math expression advances in different grades.

What is a mathematical expression.

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. Expression is a mathematical phrase which combines numbers variables and operators to show the value of something. An equation will always use an equivalent operator between two math expressions. In early grades children are expected to write math expressions using numbers and.

For example 25 7 64 2 20 5 102. A math expression is different from a math equation. A mathematical expression can be as simple as 2 4 or as complex as 4xy 8x 5 x y. Mathematical symbols can designate numbers variables operations functions brackets punctuation and grouping to help determine order of operations and other aspects of logical syntax.

2 3 is an expression 3 x 2 is also an expression. An equation is a mathematical statement wherein two expressions are set equal to each other. 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.
