1234th Post!
PikaPika999   213
N 24 minutes ago by HacheB2031
I hit my 1234th post! (I think I missed it, I'm kinda late, :oops_sign:)

But here's a puzzle for you all! Try to create the numbers 1 through 25 using the numbers 1, 2, 3, and 4! You are only allowed to use addition, subtraction, multiplication, division, and parenthesis. If you're post #1, try to make 1. If you're post #2, try to make 2. If you're post #3, try to make 3, and so on. If you're a post after 25, then I guess you can try to make numbers greater than 25 but you can use factorials, square roots, and that stuff. Have fun!

1: $(4-3)\cdot(2-1)$

Books for AMC 10
GallopingUnicorn45   0
34 minutes ago
Hi all,

So I'm in 4th grade, and I'm having a go at AMC 10 and I've got some questions.
First, how many questions are needed to get Achievement Roll and AIME?
Second, what should I grind to prepare? I took the Intro to Algebra, Counting & Probability, and Number Theory courses already, completed those three books and will be starting the Intro to Geometry book soon. I'm planning to grind the Competition Math for Middle School and try to add in Volume 1: The Basics along with the three books that I already finished, plus geometry. Is there anything else to prepare with besides Alcumus and past papers and those books?

Thanks!

AMC 10 Preparation over 6 months
raresillypanther   38
N 4 hours ago by NS0004
Hi, I'm currently in 8th grade and I have about 6 months left to prepare for the AMC 10, and I really want to qualify for AIME and get above a 100. I took the AMC 8 this year and did really bad, with a score of 16, and a 35 on the MATHCOUNTS Chapter test. I have a feeling I would get about a 70 on the AMC 10 now, so I want to be able to improve by 30 points in 6 months. Is that possible? I have summer break coming up so I feel like I could study for about 4 hours a day every single day, and I'm willing to if that's what it takes. Do you have any ideas for what resources I should use? I know about Alcumus and I have some of the AOPS books, but not all of them. If you have any tips, let me know. Thank you so much!
