Rambling on number stuff

I really don't know what I was thinking with this one.

The maths is probabbly *really* wrong.

Not gonna justify my explanation.

Sorry for dumping this text, people that read it.

The ramble

Just learned you can have a negative base on numbers.

maths is weird

OH MAN

Image of table containing "complex bases", number systems bases on things like i or √2i

*silently closes Wikipedia article*

GoodClover

Base 2 is with two symbols (101 = 5)

Base 1 is just a tally system (00000 = 5)

So base 0 would have zero symbols, and the numbers would be NaN characters long (division by 0).

(or would they be inf characters long? weird weird)

GoodClover

Hopefully a mathematician doesn't see what I said about Base 1.

In (for example) decimal 018 = 18, preceding zeroes are ignored.

zero has a value of zero, as it would in base 1, so 0 being the only symbol we can use, how do we represent a number?

the has to be at leat an "on" number and on "off" number, sound familliar?

So base 1 is actually an exception, and shouldn't be called base 1.

hehe fun, fun, fun!

This is why I like maths

i is just sqrt of -1. √(x)i is same as √(-x)

It's called imaginary number because mathematicians have no imagination

swedneck

i think a lot of people have started calling it complex numbers

since "imaginary numbers" kind of puts people off

"what, you can just make up numbers now? jesus christ i hate math"

GoodClover

They have many names, but "imaginary" is the worst as it implies they aren't real (which is wrong and correct)

test9 [EU>EST]🆔☕

> wrong and correct

Which then?

GoodClover

both

Wait I'll explain in a min

First of all you need to understand that numbers aren't real, they are just something we invented to help us understand our world.

But it matches with reality and works for that, this is usually called "natural maths" and "natural numbers" or something similar.

then we do things that are *physically impossible in reality*, such as divide by 0 or sqare root -1

Whilst these are impossible, the way our system works we can invent an answer so sqrt(-1) becomes i

(this isn't an "answer" just a representation, that was bad wording)

Anyways, the point of this is sqrt(-1) is impossible in reality but possible in our maths system.

complex numbers are a *real thing* but are *imaginary (made up by us humans)*

🛑 (reaction)

if i were to do "real correct natural maths" sqrt(-1) = NaN

GoodClover

Here, to prove my point about maths being inveted, i'ma invent my own maths (that probably already exists).

We all know dividing by zero is impossible but what if

I could say 1⁄0 = g

therefore x/0 = xg

and boom I will call this the "zero zone" (purely because it sounds cool).

I can even do normal maths to it, as *that's how our human maths system works*:

10g × (12g + 3) = 120g² + 30g

I *could* mix this with complex numbers but my brain might overheat

GoodClover

to expand it out:

1. 10g    × (12g    + 3) = 120g²    + 30g		original
2. 10(1⁄0) × (12(1⁄0) + 3) = 120(1⁄0)² + 30(1⁄0)		substitute in 1⁄0
3. 10(1⁄0) × (12(1⁄0) + 3) = 120(1⁄0)  + 30(1⁄0)		remove square — 1⁄0² = 1⁄0
4. (10/0) × ((12/0) + 3) = 120/0    + 30/0		multiply the numbers by 1⁄0 — x×(1⁄0) = x⁄0
5. (10/0) × ((12/0) + 3) = 150/0		do that addition
6. (10/0)(12/0) + 3(10/0) = 150/0		*expand*
7. 120/0 + 30/0           = 150/0		*and simplify*
8. 150/0 = 150/0		and we're done.

I've been spending too much time on this, you've been you. b-bye

(really, why on earth did I bother to do this)

Rethinking my choices on what I spend time on now

Afterwards

test9 [EU>EST]🆔☕

Why?

GoodClover

I dont know

test9 [EU>EST]🆔☕

Just simply 10g×(12g+3) ⇒ 120g×g+30g ⇒ 120×(1⁄0)²+30×(1⁄0)=inf

GoodClover

leaves screaming

test9 [EU>EST]🆔☕

Good cover.

GoodClover

I've probabbly made a big mistake in my maths somewhere too

test9 [EU>EST]🆔☕

Nah. As little as i understood it checked out

Although you slightly overslaughtered. I put 🛑 reaction where you could have stopped.

GoodClover

I know, this happens when I get tired

I explain my explanations

you can even tell from the way I worded it that everything after that reaction was an after thought, and then an after-after-thought.

Extr

If island with brits is Great Britain, then Ireland is Small Britain?

amᵃᵖanda [EU]

The Irish for Wales is "little britain"

GoodClover

Britain is England and Wales, Scotland makes it Great.

amᵃᵖanda [EU]

"Britain" has been used for~ 2000 years, Brittany in France is where the Roman Brits went after the Anglo-Saxons invaded, hence the name

amᵃᵖanda [EU]

When England (which included Wales) joined with Scotland, the Scots tried a "South Britain" (England) + "North Britain" (Scotland) thing

But the english were like "nah, we're the boss"
