1234th Post!
PikaPika999   200
N 2 minutes ago by kiwiteddy
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: $(4-3)\cdot(2-1)$

AMC 10 Preparation over 6 months
raresillypanther   38
N 2 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!

For each four--digit number $\overline {abcd}$, that is, with $a$ nonzero, let $P(\overline {abcd})$ be the product $(a+b)(a+c)(a+d)(b+c)(b+d)(c+d)$.
For example, $P(2022) = (2+0)(2+2)(2+2)(0+2)(0+2)(2+2) = 512$ and $P(1234) = (1+2)(1+3)(1+4)(2+3)(2+4)(3+4)$.
How many numbers $\overline {abcd}$ with at least one $0$ amoung their digits satisfy that $P(\overline {abcd})$ is a power of 2?

How to see the light

My subject is pretty weird but what I mean is the "light" at the end of the "tunnel" (the end of a very long post). For example, the Bogus Proof Marathon. It has like 7k replies and I really can't scroll down 7000 messages so, how do people reach the end of the reply chain? :yoda:

well if you click the post number, it gives you a direct link to use

so i guess if you scroll to the middle once, take the link, and save it, you wont have to scroll again
