expressions don't have an equal sign and equations do
I don't really think there is a difference, but maybe the difference is that in pre-algebra you learn and practice the basic foudations, like the different steps to solve an equation, and what is a equation, and stuff like that. Begining algebra is where you practice actually solving the easier types of algebra equations.
A harder version of algebra 1
Adv. is accelerated most likely.
Algebra 1 is a class/course that is on a higher level than Algebra.
Pre-algebra is essentially the basics of algebra. Algebra can be tough for many, so as a way to break the ice, you (ussually) take a pre-algebra course before algebra itself. Algebra is a very large subject, spanning multiple years of courses in most (if not all) schools. After pre-algebra, you have to work with many algebraic equations in the later courses, which cannot be understood without learning the basics that are taught in pre-algebra.
The difference of algebra and algebra 1 is that in algebra they teach you the basics. For example, they teach you about variables, graphs, how to find slopes. In algebra 1 they start using equations and and teach you how to work longer equations and all that jazz.
Yes. An equation has an "=" sign.
Both have a value

Arithmetic operations act on the values of numbers or expressions. Logical operations act on the truth-values of statements or equations.
A harder version of algebra 1
As far as I know it's an expression because it doesn't have an equal sign. That's the main difference between expressions and equations.
Algebra is a form (or subset) of mathematics.
An expression does not equate to anything. An equation is equal to something. Expression: x+2 Equation: x+4=2x Equivalent expressions: x+2 and 2x-2 if x=4 Equivalent equations: x+4=2x and -x+10=2x if x=4
Only the word "operator"
