What Is The Difference Between An Expression And An Equation

Difference between expression and equation.

An equation looks like this x 3 5 the difference between this and an expression is the equal sign formula. Equations are written as sentences with capitalization and punctuation. So let s take look at both to determine their use and relationship. The difference between an expression and an equation is that an expression is a mathematical phrase representing a single value whereas an equation is a mathematical sentence asserting equality between two quantities.

You must be able to identify and explain the difference between these key words. 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 makes complete sense as long as the equality condition is not violated. For example ten is five less than a number is an equation that can be represented by a formula.

An equation contains expressions that are separated by an equals sign. An expression is a combination of numbers variables and symbols to be calculated. An expression is written as a phrase and an equation is written as a statement. A formula is a special type of equation.

From the foregoing you can easily work out the values of the variables by evaluating the unknown variables. While an equation is a sentence an expression is a phrase. Expressions can be numeric or algebraic. An equation is two or more expressions with an equality condition and the equation is true for one or several values of the variables.

An equation has an equals sign and an expression does not. Expressions are written as phrases with no capitalization or punctuation. Also an equation is normally separated into left and right hand sides by an equal sign. It shows the relationship between two variables.
