What is the difference between evaluating an expression?
When you simplify, you are just taking the equation down to it's simplest form, not solving it. Evaluation involves actually solving the problem.
Expression has no answer. a equation has an answer
The variable.
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.
The difference between -17 and -8 can be represented by the expression (-8 - (-17)). This simplifies to (-8 + 17), which equals 9. Therefore, the difference is 9.

it has to have an x number in it.

The difference between objective and subjective perspectives in evaluating a situation is that objective perspectives are based on facts and evidence, while subjective perspectives are influenced by personal feelings, opinions, and biases.

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.
