Expression does not have an = sign

  9 − 8 is an expression

  2x + 3 is an expression

  3x − 9 is an expression

  4x = 10 is not an expression

 

 4x = 10 has an = Sign

So, it is not an expression

It is an equation

 

Here,

  9 − 8 is an expression

But it does not have a variable

So, it is an expression without variables

 

But here,

       we will study expressions with variables

 

Let learn how expressions are formed
