Can't you borrow one from a friend? Or ask if the teacher has a spare that he can lend?
@Mister C Yes its not very useful, but forgetting does get a tad awkward, if you're with people who expect you to know that sort of thing, yes.
@Telwyth Awww no hugs 
. So its not just with other men, but also with women you aren't romantically into?

No calculators allowed.
He also said that order of operations is arbitrary. There's convention now, but technically there's nothing wrong with working out addition and subtraction first.
Maths is crazier than I thought.

@Telwyth I forgot the and certain family members part. Interesting. Good luck on Friday.

Ultimately Subjective: Er... what? Order of operations matters a great deal. For example, if you have the line:
2 x 2 - 4
By following conventional order of operations, you get:
2 x 2 - 4 = 4 - 4 = 0
If you don't follow that convention, you get:
2 x 2 - 4 = 2 x (-2) = -4
These answers are not the same.
If you have an instructor who told you that order of operations doesn't matter, your instructor is incompetent.
The fact that this is how we handle it is simply convention is true, but you get entirely different answers if you do it the other way round - answers that don't make any sense, if you're dealing with real, physical problems, in most cases. Getting math to line up with reality is what led to modern order of operations.

Also, a college math exam with no calculators allowed? What kind of maths will you be tested in, exactly?

If it's calculus, that's standard, but you don't use a calculator in calculus...

Obviously you need the standard, but what he actually said was that the original setting of the standard was arbitrary.
I'm assuming that if we had have decided that addition and subtraction should always be done before multiplication and division then it would skew the way equations are written but have no net effect on mathematics as a whole.
It was just a minor aside of his. I didn't mean to imply he was advocating ditching order of operations.
My science teacher may be interesting. He used XKCD in his lecture, to show that science works.

XKCD gets used by most profs under about 50 years old, that I've seen.
And as said, order of operations is a result of requiring mathematics to give results that are in line with reality. So it's technically "arbitrary," but if we used the other methods, we would have to do a great deal more math to actually get the correct results (ie; the ones that match observations).

Well I think I got through the mid-term alright.

Back to reading pretentious Fiction Workshop stuff. Three pages of stream-of-consciousness about how everything is a LIE and there's no TRUTH and ANGST and WAR, aaaaugh. At least it's short.

So...evidently I have a Psychology test tomorrow. That I had no clue about thanks to me being snowed in both yesterday and Thursday. I curse this college and it's NEVER EVER close policy.
Also, I have to make up a History test. Funzies. Snow, I hate you right now.

I got my Spanish quiz back, with a 42/50. I was rather annoyed at myself since it was mainly due to stupid mistakes.

Wow, three weeks left... and still a lot of assignments to be turned in.

Well, that's the end for me.
I'm thinking since I don't know my times tables I'll be way too slow on exams.
