(P+L)(A+N) = PA + PN + LA + LN I just foiled your plan. Haaaaaaaaaaahahahahahahaha
I love math puns.
OK, I'm either A) stupid, or B) tipsy from wine and a looooooooooooong day but I'm not getting it. Would someone be a peach and spell it out for the pea-brained in the group?

Multiplying out (A + B)(C + D), one gets four terms: AC (by taking the First terms in the two expressions), AD (by taking the Outer terms in the expressions), BC (by taking the Inner terms in the expressions), and BD (by taking the Last terms in the expressions). Hence the word FOIL is a mnemonic to help students remember First, Outer, Inner, Last. Hence "FOILing" a plan.

Sum Dum GaiDid you complete any classes at the community college when u were a teenager? If so, you may not need to take an assessment test. There is a difference between a "new student" and a "transfer student". Even if the other classes were a zillion years ago, they may consider you a transfer student. My DH and I both went to community colleges in the past 5 years for various classes. I had my transcripts sent from my classes in 1998-2000 and DH had his sent from his BA (1995-2000) and no assessment tests were needed. They let us enroll in the courses which were the next ones up from what we took back then (I took Business Calc in 1998 and they let me enroll in Calc 1, same for DH).

Looks to me like it ends up being an anagram for... somebody here on this thread. Or at least who they used to be. And since multiplication is commutative, it's not really an anagram after all.... Is it?
I'd show the work, but I usually didn't as a kid anyway. I'd hate to set a precedent. And besides, other people may want to keep trying.

So, I'm going back to school. They're requiring me to take the math/english placement test. Obnoxious, but whatever. No big deal right? I scored a 32 on the ACT the first time I took it, with no prep whatsoever. My morning went a little something like this; Well, it has been a while since I was in school. Maybe I'll check out the practice questions on the math side. I'm probably a bit rusty. Logs onto the student portal. Finds the assessment section. Finds the practice questions. Gets about three problems in, half guessing on the first two. Problem three is something that I definitely know that I knew how to do at one point. Now though, uh... something with pi... or one of those equations I used to have memorized that my algebra teacher insisted I would need one day that I internally thought were completely useless.... uh... think damnit, you can do this... I think I'm supposed to simplify some stuff and move the x around or whatever... ah fuck it, just guess... sure C. It's always C. Problem 4... what the shit... is that even math... it's like a wheel of fortune puzzle without any vowels. I'd like to solve the puzzle Alex, some weird Asian saying, or maybe a town in southeast China, not sure exactly, but it's got way to many x's and y's in it to be English. Alright, take a break. Calm down. Drink coffee. Yeah coffee, that'll get the old noodle going. Back to the practice questions. Not even going to look at 4 again, screw 4, it's got more letters than numbers in it. Should be on the english part of the test. Question 5... uh.... crap. Question 6... wait wait wait I know this one. Sweet. 1 for 6 baby. Question 7... bummer. Question 8... damn. Question 9... holy crap. Question 10... why did I schedule the exam for Saturday morning. Question 11... I'm fucked. Question 12... I'm going to spend an extra two years in college just taking remedial math courses. Question 13... why am I still looking at these, it's clear I can't do math anymore. Question 14... dude, just stop, seriously, you're a moron now accept it. Question 15... No really, just stop. Question 16... fuck you buddy, I'll accept being a moron, but I won't be talked to like that by my own internal voice, asshole. Question 17... alright, you might have had a point, these things are just freaking me out. So yeah. Happy Thursday everyone.
On the bright side, you're still probably good enough to get married in India. If you weren't already, that is.

Kind of. I'm going to school because I regret not going the first time. Well, finishing/going. It's complicated. Not that complicated. I dropped out of high school to attend community college full time when I was 14. Planned to get an associates then transfer to a university. Instead I dropped out. Have always regretted it. I also have the post 9/11 GI Bill so I can go back to school for basically nothing out of pocket, and get paid to be a student. Might as well take advantage. I need to get back on my feet anyway. At some point I need to figure out the answer to the what do you want to be when you grow up question. Same thing it does for anybody; get my foot in the door in my chosen profession. I just haven't chosen one yet. Look for a workshop at the CC for career/major exploration. Colleges often have an assessment test for that as well, which can help you determine if you prefer to work with people, things, data and I think there was one more thing. The quicker you can pick at least a general direction, the better (i.e. business, science, etc.). Even if all your Gen Ed classes transfer, there is a way to pick specific classes within that framework that will get your degree complete in 4 years total. Otherwise, you may find that you have to take additional classes at the state college that could have been done within your Gen Ed. It's good to know exactly which state U that you are planning to transfer to, because they'll have specific equivalencies for classes listed somewhere on their website. It sucks if you take a class at the CC, and basically have to repeat it at the state U because they don't count the CC's version of it. Some classes that seem to transfer fine, from my experience: English 1 & 2, Calc 1, Statistics (basically the Freshmen level--Sophomore level courses are more tricky)

Ok, I totally lost the ability to keep up several posts ago. 1. Virgil Showlion - Thanks for explaining "foiling" a plan. I knew I was missing something on that. 2. finnime - thanks for showing the solution. I tried for all of 8 seconds before going to whimper quietly in a corner. This is why I argue that I don't really have a STEM degree.

FWIW, I think it was nice for Finnime to type all that out and be willing to show her work. I don't have that much patience and it is good she does.

It's as simple as respecting multiplicative axioms during exponentiation, canceling common numerator/denominator factors, applying distributive laws to products over the reals, eliminating redundant terms with opposite sign, respecting operator precedence, and exploiting the commutative nature of the variables to obtain a multivariate polynomial in canonical form.

Your lips say "no", but your raising the subject ex post facto says "It should be me getting that super-like. " Let it be known that Tall was technically the first one to correctly solve the problem.

I don't think there is a prize for making things sound more complicated than they need to be. At least I hope not.
You must have a heck of a memory for terminology. I don't. I needed that post to explain why FOIL was funny. Don't remember that at all, but maybe in the dark ages we just did the math and didn't give it a name.

I have a minor in math... I got an A in Differential Equations and Advanced Linear Algebra classes... and I swear, I can't do 6th grade math. It's just bizarre.
Sorry to hear about the store, DH. Have you considered going back into the military?

I just want to demurely raise my hand here and point out that tallguy did reference the answer, he did not, in fact, solve it on this forum. And in my current state of being, I will toil slavishly for Likes, including those that nod at my math minor. A girl's got to glean 'em where she finds 'em. Like me! Love me! Like me most!! Now, for an aptitude test: what does this mean? {} answers below for STEM-oriented people, this is a null set. for everyone else, it is a butterfly. if you see both, note that you have schizophrenic leanings.

The answer to the second will answer the first one. The store is closing at the end of the month. It's time to pull the plug and do something productive with myself. That also means I'm 33, about to be unemployed, a high school and college dropout, the only experience on my resume is military and DoD IT stuff but I have a two year gap, and my clearance is going to lapse sometime next month. I'm more or less at the same point in my life that I was at 18; broke, unemployed, limited marketable skills. Seemed like a good time to go to college. I thought you said your fallback if the store didn't pan out was to go back to the 6-figure IT stuff, in a different job that you won't hate so much? Personally, I'd focus on that. You're in silicon valley. Tech jobs should be plentiful. They are in my much more buttf*cky, midwestern city. Explaining away a 2 year gap due to trying to start your own biz is perfectly valid and shows ambition. It's not like you sat on your ass during that time. And if you're worried about obsolescence, take some refresher courses in the latest technology. The lapsing clearance shouldn't be that big of an issue. The fact that you have/had a recent one at least tells an employer that you're clearable. Hell, I didn't have one at all when interviewing for my current job. They had to sponsor me, and pay the price to get me one. Getting a degree in something different means you'll have to incur the direct and opportunity costs of that, do all of the work, and then end up starting out at the bottom with the rest of the new grads (with commensurate salary) when you're done. And that's if all goes WELL. Personally, I wouldn't bother unless you REALLY don't want to go back into IT, are willing to pay the (hefty) price to do something different, and if your new degree will be something that's almost guaranteed to show you the money. But that's just me.

I feel like such a dumbass. I took the arithmetic section of the posted test and got 18/20. One was an obvious mistake but I can't work out how to get the correct answer on the other one. It's driving me crazy! Can someone please solve this (and show their work)?
Erica bought 3 1/2 yards of fabric. If she uses 2/3 of the fabric to make a curtain, how much will she have left?
a. 1/6 yd b. 1/3 yd c. 1 1/16 yd d. 2 1/3 yd.
The answer is C but I keep getting D and can't work out what I'm doing wrong with the formula. I don't think I'll even attempt the algebra section now .
