An equation is simply a statement in math in which two things on equal. There are two expressions, one on each side of an equals sign. For example: X = 7.

An expression is a sentence fragment that stands for a single numerical value. On the contrary, an equation is a sentence showing equality between two expressions. The expression is simplified, through evaluation where we substitute values in place of variables. Conversely, an equation is solved.

Expressions are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division.

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

Understanding Expressions and Equations You can define a numerical expression as a group of numbers and variables with no equal sign. An equation is a group of numbers and variables that does include an equal sign. And, you can simplify equations and write expressions and equations.

Difference between Algebraic Expression and Equation An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

Understanding Expressions and Equations You can define a numerical expression as a group of numbers and variables with no equal sign. An equation is a group of numbers and variables that does include an equal sign.

We can say that an expression is a random combination of numbers, variables, functions, etc. For example, 3x – 2 is an expression. While on the other hand, an equation means that two different expressions are connected to each other by an equal to sign in between, For example, 3x – 2 = 5 + x is an equation.

An expression does not reveal any relationship while an equation does. An equation contains an ‘equal to sign’, therefore, it shows solution or ends up representing the value of the variable. However, in the case of an expression, there is no equal sign, so there is no definite solution and cannot end up displaying the value of the variable involved.

An algebraic expression is a mathematical phrase that can contain numbers and/or variables. It does not contain an equals sign and cannot be solved. An algebraic equation, however, can be solved, and does include a series of algebraic expressions separated by an equals sign.

The primary difference between an expression and equation is that an expression doesnot contain any equal to sign whereas an equation contain an equal to sign.

An equation sets two expressions equal to each other. A variable is a symbol used to represent a number. In the expression 8x + 17, x is the variable. In the equation = 25, y is the variable. Variables need not be letters; for example, the expression 6 + 2 contains the variable . An expression or equation may contain more than one variable.
