RIP School Survival Forums
August 2001 - June 2017

The School Survival Forums are permanently retired. If you need help with quitting school, unsupportive parents or anything else, there is a list of resources on the Help Page.

If you want to write about your experiences in school, you can write on our blog.

To everyone who joined these forums at some point, and got discouraged by the negativity and left after a while (or even got literally scared off): I'm sorry.

I wasn't good enough at encouraging people to be kinder, and removing people who refuse to be kind. Encouraging people is hard, and removing people creates conflict, and I hate conflict... so that's why I wasn't better at it.

I was a very, very sensitive teen. The atmosphere of this forum as it is now, if it had existed in 1996, would probably have upset me far more than it would have helped.

I can handle quite a lot of negativity and even abuse now, but that isn't the point. I want to help people. I want to help the people who need it the most, and I want to help people like the 1996 version of me.

I'm still figuring out the best way to do that, but as it is now, these forums are doing more harm than good, and I can't keep running them.

Thank you to the few people who have tried to understand my point of view so far. I really, really appreciate you guys. You are beautiful people.

Everyone else: If after everything I've said so far, you still don't understand my motivations, I think it's unlikely that you will. We're just too different. Maybe someday in the future it might make sense, but until then, there's no point in arguing about it. I don't have the time or the energy for arguing anymore. I will focus my time and energy on people who support me, and those who need help.


The forums are mostly read-only and are in a maintenance/testing phase, before being permanently archived. Please use this time to get the contact details of people you'd like to keep in touch with. My contact details are here.

Please do not make a mirror copy of the forums in their current state - things will still change, and some people have requested to be able to edit or delete some of their personal info.

Math homework I need help

I suck in proportions, so if anybody here can help, I will be grateful.

Here are the questions ( the ?/? are fractions):

B) m/15 = n/6, m - n = 90
C) r/s = 13/5 , r - s = 72
D) 18/x = 8/y, x + y = 104
E) x/8 = y/3 = z/4, x - y + z = 108
F) 15/x = 9/y = 3/z, x - y - z = 42

This is middle school stuff I think, so it shouldn't be so hard to solve them if you are good in Math. I will be grateful for whoever does this for me.

Math homework I need help

I'm too lazy to do these right now, but, the general way you do these is:

1) rearrange the proportions such that you get the variables in the numerator.
2) on the right side, (m-n = 90 etc.) solve for one variable
3) use that information and put it into the proportion

like for B)
m-n = 90
m = 90 + n


substitute m = 90 + n for m
(90 + n) / 15 = n / 6

dive 90 + n by 15
6 + (n / 15) = n / 6

subtract n / 15 from both sides
6 = (n / 6) - (n / 15)

Solve for n. Once you have n, put n back into the original equation you start with, then solve for m.

RE: Math homework I need help

freaking smart-ass middle schools...this is what we were learning last semester and i sucked at them because the teacher was dull, demanded respect and never gave you any, and literally put me to sleep even if i was wide awake.

I ended up getting a 57% in his class so i'm in the repeat class for algebra 2 with a better teacher (i know because i had him before and used to go to him all the time for help during study hall)...i do wish that i would have worked just slightly harder to be able to have passed first semester

The less you try to control things, the less you need to.

"free speech under the constitution only guarantees the government won't stop him saying it and does not guarantee his right to say things and have no consequences at all as a result. also i completely doubt that he is motivated solely by "i'm saying it because i can" and is probably motivated by a more shitheady motive like "i think it's funny to annoy people and Rustle Le Jimmies™ and is just hiding behind the first amendment to try to deflect any consequences or make you realize that being allowed to annoy people is a superior moral right. you can still disdain someone for doing things for dumbarse wankery purposes and you have evne more right to ban and insult them for it" ~Trar's friend about Potato.

Thanks for the diploma… can I have my childhood back?

I’d love to have a battle of wits with you… but I hate to fight the unarmed.
