it depends what textbook you have. basically it's ratio, proportion, division of fractions, the pythagorean theorem, surface area, volume, compound and simple interest, markup and selling prices, formulas, simplifying exponential expressions, and so on. there's a lot more but this is some from the Foundations for Algebra series. Hope this helps!

I am in 7th grade and I am learning pre-algebra but in my school we learn a grade ahead so I think its not normal for people to learn pre-algebra in 7th grade, but its possible.
HELL NO! If you like algebra, even pre algebra, there is something wrong with you.
No, Pre-Algebra is a little bit less complicated, it is what you learn before algebra.
Pre-algebra is where you just learn the basics of Algebra and Algebra two is way more advanced with new information and taking the concepts you learned in pre-algebra and algebra to the next level.
The Latin prefix pre- means "before" so Pre-Algebra means "Before Algebra". Pre Algebra gives you the bottom bricks or the foundation of your math building. This is the most important mathematics year of your life so try not to mess it upalgebra is harder.
