Technically, that statement might be true   Since some rectangles aren't squares.  But yeah early school taught me that squares weren't rectangles, and learning the truth was like an introduction to set theory.

If you evaluate it RTL.  Sadly, phones do not have whatever symbol means "is subset of".  But yeah, they tried to tell me squares were not rectangles in fourth grade, and then TURNED RIGHT AROUND IN FIFTH GRADE.  Seriously.

as going into a fourth grade class and hearing the students chanting multiplication tables (a method that was once used for brute-force memorization as the "proper" way to teach math)

This is how I learned multiplication.

In the 2000s.

Gosh, that was painful. I was normally ahead of my class but I lagged behind quite a while when we got there and I kept doing the tables long after everybody else was done because I don't learn well at all with brute memorization.

You mean \subset ?

I read != as equivalent, IE in both directions. Might depend on context since I don't think it's real notation outside programming languages...

Well actually, it would evaluate as true in any actual program context.
The set of all squares is not the exact same thing as the set of all rectangles, let alone dealing with ordering.  But I meant it to be read (Assertion that) "Set of all squares is not subset of set of all rectangles".

You can do that?  RAEG.  RAEG at all the weird set notation stuff!!!

imgur is having problems. My plan is to give it about a week before I try to find somewhere to migrate to, if the problems continue.

Finished my calculus test. Oh god, someone kill me and put me out of my misery. So much math. So exhausted. I swear I did 8 out of 20 problems wrong because I kept getting the same answer for each problem (zero) so I'm fairly certain I did something wrong and two of those eight I didn't even have time to get to and uuuuuugh I definitely didn't get an A.

This is only the first test of the class and there's going to be 4 or 5 more tests and opportunities to raise my grade to make up for this first awful test but I feel terrible about it nontheless because I flubbed up. I could've done better if I hadn't wasted most of my weekend playing vidya games.

If your answer is f(x) (or limit)=0/0, you have something you need to simplify out.  And a domain restriction.
I don't know if that actually helps you any...Dang it, the sad is contagious.
All the same, GL.

Its a useful skill to have if you actualy hand write things often,

Provided, of course, that no one will ever be called upon to read it

Either 0/0 or num/0 or 0/num. Woo, great, awesome, I definitely got some stuff wrong. In any case it's too late now. (ノ oДo)ノ ︵ ┻━┻

I just didn't learn them. Git gud at mental maths son.

I find that I write faster NOT in cursive.  Mostly because my handwriting kind of resembles it anyway.  Only less legible.

@Spehss_:  0/something is probably valid.  Something/0...Yeah, not so much.
