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?

FTW and AMC Prep Forum
PatTheKing806 252
We (PatTheKing806 and Sadas123) have created a private forum for people to do math with friends. I believe this is the funniest and the most joyful way of doing math problems. There are currencies to motivate people to get #1 on the leaderboard.
This is similar to the 'AMC 8 Prep Buddies' Forum, but if anybody wants to join, just type, /join and one of us will add you. This is also a FTW Forum if you are curious too!
Here is the link to our forum. See you there!

How to deal with complicated geo diagram?
WheatNeat 2
I've recently been doing more complicated geo problems and it's been getting harder and harder to actually decipher anything from a diagram with all the lines and stuff. Sometimes the lines even get too close and it's hard to write stuff on it. Do you guys break down the diagram into smaller parts or do you just get good enough to see everything with the raw diagram? Also how large do you guys draw your diagrams?

9 AMC 10B cutoffs
FuturePanda 185
Hello good people,
On the flip side now! I answered 17 and think I sillied 2 so 102, what do y’all think the cutoff from AIME will be for the AMC 10B?
Oh and reply saying if the test as easier or harder too!
Without further ado, the poll to end all polls for the 10B!

[*]How did you prepare?
[*]What was your confidence level?[/list]
[*]Which problems did you get wrong?

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.
