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.

Expression in math example.

Scroll down the page for more examples. An equation is a mathematical statement that tells you that two things have the same value in other words it s a statement with an equal sign. Just as 2 x means 2 times x 4 xy means 4 times x times y. A 14x 5x 14 5 x 19x.

Math students are often asked to give their answer in the simplest terms in other words to write answers as small as possible. For example while 2 2 is an expression 2 2 4 is an equation. A 14x 5x b 5y 13y c p 3p. The expression 9 x represents a value that can change.

Variables may also be in the denominator of a fraction as in the expression 7. Write each phrase as an algebraic expression. The equation is one of the most important concepts in mathematics because it allows you to boil down a bunch of complicated information into a. In early grades children are expected to write math expressions using numbers and.

In these lessons we will learn what variables constants terms expressions and coefficients are in algebra. A math expression is different from a math equation. Though a long ungainly expression and a short elegant one may technically equal the same thing often a math problem isn t considered done until the answer has been reduced to simplest terms. The following diagram shows some examples of like terms.

In the next few examples we will be working solely with algebraic expressions. An equation will always use an equivalent operator between two math expressions. If x is 2 then the expression 9 x has a value of 11. The ideas of equality expressions and evaluation are vital concepts when working with equations.

Algebraic terms expressions in mathematics often the value of a certain number may be unknown. If x is 6 then the expression has a value of 15. For example 25 7 64 2 20 5 102. So 9 x is an algebraic expression.

Like terms can be added or subtracted from one another. Scroll down the page for more examples and solutions on simplifying expressions by combining like terms. The following diagram gives an example of algebraic expression. Although the term is associated strongly with algebra children are taught mathematical expressions from the moment they are handed worksheets containing the simple expression 2 2 equations and inequalities are special mathematical statements that compare expressions.

An example of a multivariate expression is 4xy 5x 7. Mathematical symbols can designate numbers variables operations functions brackets punctuation and grouping to help determine order of operations and other aspects of logical syntax.
