An equation is a statement that two things are equal; it has an equal sign which looks like this: =

So if, for example, 2x + 5 = y4 - 27, that's an equation. A collection of numbers and/or letters that does not have an equal sign would be an expression. For example, 3x(9 + x).

What is the difference between expression and equation?

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."

What is the difference between an expression and an equation?

An expression does not include an equals sign (=) For eg: 2x+3 would not be an equation but an expression However, 2x+3=0, is definitely an equation with a solution x= -3/2. An expression does not have a definite solution. An expression is a set of terms with mathematical operations combining them. An equation consists of two expressions with an equals sign between them. An expression is a collection of terms and does not have an = sign An equation is a collection of terms but has an = sign between them.
