I'm a freshman in high school and I'm taking a SAT prep course my district is offering. We have workbooks and stuff and we have the Official SAT Study Guide, that monstrous, huge, book. I went through the whole math section (because my score is only a 550) and picked out the questions labeled "hard" so I could have a better understanding.

I worked through all of them and I have 20, no exaggeration, that I absolutely cannot understand.

Here's an example.

If n and p are integers greater than 1 and if p is a factor of both n+3 and n+10, what is the value of p?

I've tried calling my teacher (who gave us his cell phone number), but he didn't answer. I would ask my math teacher, but he doesn't tutor on the day I would have to go.

If you think you can help me, you really good math people, please reply or PM me.

Unfortunately, I've forgotten all of my algebra. The last math class I took was for wallpaper patterns.

I'd help you if I could. :(

xD Thanks. I appreciate it.

I registered for a math help forum and figured out why y=5. I'll replace that one with another example soon.

Oh my - I can do Calculus - but I can't for the life of me remember how to do stuff like that - I used to HATE it D: XDD Good luck!!!

n=4, p=7

I just guessed and checked to see what numbers would work, and these did. These questions won't have crazy numbers for answers, so just start low: 1, 2, 3, 4, etc. Also, I believe that the SAT is multiple choice, so just plug in the answer choices given and see what works. This strategy makes many math problems much easier on these tests, so it can help you get through them quicker.

Hope that helps!

Feel free to post any more you are stuck on. :)

I was just about to say the same thing, kreest, before I read your response.

Most questions like this in the SAT can be figured out by just trying. Don't be scared of them. <3
