What is the difference between evaluating an expression?
Simplifying an expression is getting rid of any brackets or parentheses, performing as many operations as you can - including combining like terms. To evaluate an expression you would substitute the numerical values of all the variables, carry out all the operations (addition, multiplication etc) in the expression to reach the answer - the numerical value of the expression.

it has to have an x number in it.
A variable expression includes variables.
The difference is that an algebraic expression has numbers, symbols and variables, but a verbal expression has only words.
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.
