Expression has no answer. a equation has an answer

An expression has no equal sign whereas an equation does have an equal sign

An equation has an equal = sign whereas an expression does not.

An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.

an equation has an equals sign.

The difference between these two is that an expression only contains variables, numbers, and mathematical symbols, and an equation contains two expression with an equal sign that separate them. For example, while an expression is "2x-1", an equation is "2x-1 = 5x."

Simply put, an expression does not need an equal sign, while an equation does. Equation: x+y=z Expression: x+y

similarity: both involve arithmetic operations and/or functions difference: an equation either produces an answer or shows how two expressions are equal, an expression does not produce an answer and is usually a portion of an equation or a larger expression

simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >

A numerical expression is an equation that contains only numbers. An algebraic expression is an equation that contains one or more variables and can also have numbers.

Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)

Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
