What does a number followed by a letter in algebra mean?
Oh, dude, like when you see a number followed by a letter in algebra, it means you're dealing with a term where the number is multiplying the letter. It's like saying "hey, little letter, you gotta hang out with big number over here." So, if you have 3x, it's like saying 3 times x, which is just math's way of keeping things interesting.

Do you have to remember algebra 1 to do good in algebra 2?
To do WELL in Algebra 2, you will need to remember part of Algebra 1. However, your teacher should go over part of Algebra 1. I did poorly in Algebra 1, though Algebra 2 now makes sense to me simply because I needed to understand it to understand Algebra 2, and I was able to infer the things that I was unsure of.
