Number Sense Marathon (Mental Math)
brainpopper 535
Number Sense Marathon
Hi, there isn't a number sense marathon that I know of so i'll just make one.
READ THESE RULES:
1. All calculations must be done in the head. No calculators, no paper, no writing.
2. Make problems doable. If you deem a problem too hard, skip it.
3. Please don't fight over a solution or something ridiculous.
4. Use hide tags for your problems and solutions.
5. Make all problems actually number sense. You can find a practice test for number sense here (thanks davidaops)
Don't know how to solve half the problems? Learn some tricks for mental math here.
Please make sure to follow the following format:
To post and hide your solutions, use the S# P# format. It looks like this:
[quote=User1]
S5
P6
[/quote]
[quote=User2]
S6
P7
[/quote]
To use hide tags, simply do
[code]P5
P5
If you'd like to make your problems and solutions fancy, you can use LaTeX.
Lastly, please don't post if you don't know what you're doing.

Questions about dividing by 0
Arr0w 28
I have a couple of questions all of which have to do with dividing by 0. Thanks in advance.
1
2
3
4
5
1
is considered undefined, but . How is this possible if its reciprocal is undefined?
2
Would be considered a rational number? Or would it be in a class of its own?
3
I think this statement would be true: . How is this possible if is undefined? Would this make it a rational number then, given the fact that any number over itself is equivalent to ? I put in my calculator, and it just reads an error, but wouldn't it be 1?
4
What exactly does "undefined" mean numerically?
5
Originally, complex numbers emerged because the square root of a negative number is impossible, and complex numbers give a proper explanation. Why haven't they done this with dividing by 0? Has this already been done?

Hi everyone,
I think I got an 81 and 102 for 12A and 10B, sillying way too much on both. I read all of the AOPS books, and I know most of the theorems for the AMC’s I just don’t know which ones to apply to solve the problems. Additionally, I suck at trig, complex, and logarithms. What should I do to improve?
For example, should I be grinding past AIME’s?
I plan on reading most of the Awesomemath books for L3

USAJMO cutoffs... will I make it????
zcsharon 6
Hi guys so I got a 123 on the 10B and 118.5 on the 10A, when I should've gotten 136.5 (I misread 3 :sob emoji). What score do I need to get on the AIME to make JMO?? I think 11 is like a 90% chance because of the cheating last year only had 232 on the 10B... But a lot of people also say that it's high 230's, even maybe 240's. Who should I believe and what score should I aim for??? :)

USAJMO cutoffs
Schintalpati 28
I got a 145.5 on 10b, could I slide with an 8 on AIME? Or would I have to get at least a 9-10? And also, if it was an harder AIME based on the 10b difficulty and general demography of how people did, what’s the lowest cutoffs could look like? I didn’t make AIME last year, so Idk much about cutoff predictions. Thanks

There is still time to train for the November 6th and November 12th AMC 10A/12A and AMC 10B/12B, respectively! Enroll in our weekend seminars to be held on November 2nd and 3rd (listed below) and you will learn problem strategies, test taking techniques, and be able to take a full practice test! Note that the “B” seminars will have different material from the “A” seminars which were held in October.

For those who want to take a free practice test before the AMC 10/12 competitions, you can simulate a real competition experience by following this link. As you assess your performance on these exams, be sure to gather data!
[list][*]Which problems did you get right?
[list][*]Was the topic a strength (e.g. number theory, geometry, counting/probability, algebra)?
[*]How did you prepare?
[*]What was your confidence level?[/list]
[*]Which problems did you get wrong?
[list][list][*]Did you make an arithmetic error?
[*]Did you misread the problem?
[*]Did you have the foundational knowledge for the problem?
[*]Which topics require more fluency through practice (e.g. number theory, geometry, counting/probability, algebra)?
[*]Did you run out of time?[/list][/list]
Once you have analyzed the results with the above questions, you will have a plan of attack for future contests! BEST OF LUCK to all competitors at this year’s AMC 10 and AMC 12!

Mathcounts Trainer Issue
booking 9
Hi, I think Mathcounts Trainer has a little problem. The problem is that Mathcounts Trainer keeps taking forever to load my answer and when I refresh and put it in again, the next question I get is the incorrect question, so I end up doing the question for no purpose. :wallbash: Can someone please verify or fix this issue please? Thank you.
