Shitpost and Notation

Care to elaborate?

The solidus is / right?
In different contexts it means different things.
For example, if [math]G[/math] is a group and [math]N \leq G[/math] is a normal subgroup, then [math]G/N[/math] represents the quotient group. Some people like to pronounce it as "[math]G \text{ mod } N[/math]".

It's 10.

Real men don't have problems like this.
Real men use postfix notation.

I never did differentiate before, but I like how this symbol is used. It'd be quite useful for writing neater expressions inline with text - e^2 / (2h) just looks ugly

>lol look at me I wrote purposefully ambiguous notation, let me post it all over social media and make fun of everyone who 'can't do first grade math'

This is literally what normies think math is or something? It's like if someone mumbled his speech, and the listener went "what did you say? I didn't catch that," to which the mumbler would shout "Ha, I guess you don't even understand basic English! what an idiot."

Absolutely pathetic.

Inline it looks fine [math]\frac{e^2}{2h}[/math].

What? No, it's not better because 1) it's ugly and 2) it's ambiguous (partly because no one uses after elementary school, but that's because see point 1).

The beauty with the solidus to represent inline division is that you can write expressions like [math] e^2 / 2h [/math] and the reader understands that, without any ambiguity, it is the same as
[eqn]\frac{e^2}{2h}[/eqn]
whether there are delimiters or not. (This is possible because of the elegance of shorthand multiplication notation.) Clearly, you cannot do the same with the [math]\div[/math].

>quotient group
You know why that notation was picked for that?
Hint: quotienting groups should be reminiscent of division in many ways

>Gorram
Get the frack out of here with that shit

6^2 / 2(3) + 4
36 / 6 + 4
6 + 4
10

It's intended use was clearly defined- and thousands of people are getting it incorrect.

Good to know.

Sorry not sorry bra.

÷ is not the same as /

/thread

It was clearly defined... by several sources differently. The current global standard is that all division is simple division unless otherwise stated.

Failed first term user?

Yes, but it does not mean "divide" in the same sense that OP thinks it means. In some ways, since it must be a normal subgroup, you can definitely think of it as dividing by a "factor" however.

Definitions in maths are subject to source.
e.g. some authors take neighbourhoods to be open in topology.

If I was a mod, I would ban anyone who posted this troll garbage for 1 day on first offense, escalating it for further offenses.

Should ban most of Veeky Forums for responding to this troll garbage.

It was nice back when we could see who was sageing.

says a namefag

5÷2 = 1
5÷2 = 2.5
5÷2 = 3

depending on whether you read it as modulus, division or subtraction.

This if from a Berkely site with a book on teaching pre-algebra.
"[m/n] = the length of one part when a segment of
length m is partitioned into n equal parts.."
Originally the m/n was vertically annotated.

"...m ÷ n is the length of one part when a segment
of length m is partitioned into n equal parts."

Let m=6^2
And n=2(3)+4

people used to do something similar in school all the time with homophones.

>say something that could mean 2 different things
>mock the person when he assumes the common meaning

also, you do get the mumbling thing as well:
>Losersayswhat?
>what?
>haha, you admit it! your a loser!

>wander into here from another board hoping to learn something new
>order of operations is unknown

W E W

>wander into here from another board hoping to learn something new

Don't ever come to Veeky Forums hoping to learn anything, everyone is fucking 16 and stupid here.

6^2 first

2(3) second

36 /6 third

6+4 fourth

you're either not reading the thread and don't know what's being argued about, or you're taking troll posts seriously... either way

Will common core fix this rampant ignorance?

lol ur dumb
