ok ?

[ask-numberjacks]

what do you guys think of this fanfic? https://www.deviantart.com/majestical4729/art/Numberjacks-More-Math-S1E1-858057085

My handwriting is awful istg

I agree with Five. It was really interesting! It'd make for a great episode if it was canon.

Edit: I take those (the watch/fav) back since apparently the author is homophobic >:(

Zero, Negative, and Infinite Numbers in Antiquity

With the advent of accounting, numbers became more important to people of the Bronze Age and into the Iron Age. Numbers grew into a thing of philosophy as much as they were of accounting and geometry. Number systems were developed, based on systems of 10, 20, or even 60, depending on the culture, but numbers having a value based on where in the number they appear, such as the value of 4 being different in 4356, 43, and 354, was something that came along later. This is something we take for granted now, but wasn't developed until the Hindu people of India. The biggest development that allowed for a positional system of numbers is 0.

Zero shows up in some ways before the Hindu-Arabic numeral system was formalized. The Ancient Egyptians used a symbol called 'nfr' to symbolize when the amount received by pharaoh was equal to what was distributed, but they did not use a positional system when writing other numbers. The Babylonians also didn't use a positional number system, though they might use three hooks, or later two slants, as punctuation marks between between numbers like we use zero now, but they were never used alone or at the end of a number, showing that the concept wasn't fully developed yet.

The ancient Greeks seemed to be philosophically opposed to zero while also needing to use it for their astronomy. They used lower case omicron (ό) initially in place of the punctuation marks that the Babylonians used. The quantity of zero led to the philosophical question 'how can not being be?', on which the paradoxes of Zeno of Elea rest (one of which being 'that which is locomotion must arrive at the half-way stage before it arrives at the goal').

The ancient Chinese used a counting rod system that allowed positive and negative numbers depending on how exactly the numbers were written, but treated zero itself as a vacant place, lending the system a type of positional set up, but without having a zero or null concept. At some point prior to CE 1274, the symbol 〇 as the placeholder and was probably borrowed from the Indian people.

In India, a black dot was used as a symbol for zero, which gradually became hollow. It was fully recognized as a number as far back as CE 224, though Pingala, a Sanskrit scholar who lived around the 2nd or 3rd century BCE, created a type of notation similar to Morse code with long and short sylables and included a zero, using the word Śūnyatā शून्यता to represent zero. The word is generally translated as 'insubstance' or 'nothingness'.

Negative numbers are a part of accounting, so they existed from the beginning of the idea of counting. The only known group of peoples to have specific notation for them, though, are the ancient Chinese with their counting rod system.

In ancient cultures, infinity wasn't a number, but an idea to be explored through philosophy. The earliest record we have of this discussion is Anaximander, who lived from about 610-546 BCE, who called it apeiron ἄπειρον, which is translated as 'unlimited, boundless, indefinite'. He considered this to be the basis of reality. Anaxagoras, who lived from about 500-428 BCE, believed that the universe had the capacity to be infinitely divided (leading to the idea of atoms). Aristotle (384-322 BCE) rejected the idea that infinity was a real thing and could only be an idea. Aristotle's ideas were not widely disputed until the Enlightenment.

Early Indian thinking on infinity was written into the Jain upanga Agamas जैन साहित्य around 400 BCE. There it is held that numbers can be divided into three groups: enumerable (lowest, intermediate, highest), innumerable (nearly innumerable, truly innumerable, innumerably innumerable), and infinite (nearly infinite, truly infinite, infinitely infinite). They were the first group to recognize that not all infinites are the same, which corresponds with the modern mathematical thinking. Infinite length, infinite area, and infinite volume are all infinites, but not the same infinite.

How does negitive power interact with Cut Down? -Destil

Quite well!

Normally, Magic doesn't like negative numbers, but it's fine with them existing in power and toughness and the math for them works just fine when calculating a total P/T for Cut Down.

For example, Cut Down will see that an unmodified Char-Rumbler has a total power and toughness of (-1)+3=2.

are negative numbers real? are they the same numbers but they use a funny hat (-)?

(no)

opinions on -7?

i love -7

[waspsinyouryard]

Ok so

Let's just say I have the incredibly challenging task of figuring out what 6 + (-4) is. Instead of being like "ah this is 6 - 4" I would would imagine that a battle is occurring, and one side has 6 soldiers and the other has 4. Then, slowly, the soldiers would kill each other 2 at a time until only 2 soldiers remained, both on the positive side. Then, since 2 remain on the positive side, I would know the answer is positive 2.

Or I could just solve 6 - 4

Never even in death will you lose your fame, but you will be in men’s thoughts, your name ever immortal... (Theognis 245-246, trans. Gerber 1999).

Sometimes, the niche crossover urge takes over. This is based on Greek red-figure vase paintings of kithara players (specifically the ones here and here). If you want to hear a little about how the kithara is played and a little sample of improvisation on the instrument, check out the video here!

I like that the way you talk about middle aged men is almost misogynistic

slaps that old mans ass and says "youd be prettier if you smiled more"

[locusfandomtime]

The maths fandom is wild. “Real” and “imaginary” numbers? I think you mean canon and non-canon. You guys seriously go “this is my number oc his name is i and he is the square root of -1” when in numbers canon lore it’s actually impossible to square root a negative but sure whatever. “Complex numbers”? I think you mean a character x oc ship. “f(x) = 3x - 5”? That is self-insert fanfiction.

This angel has another question! \o

Hiiii ! So, for all the angels having chronic anxiety disorder like me, how Ren would take care of you if you had a panic attack because of that ? Not because of a precise event, but something angel was going trhough since forever but now has Renren to take care of them during those ? I would love to see !

I give a warm hug to all the angels living this ! ♡

✦゜ANSWERED: As someone with AvPD and SAD, I can relate to this ;v;

Realistically though, it's kinda hard for me to give a precise answer to these kinds of questions (not just anxiety-related ones) as it's different for everyone.

That said, I think Ren's reaction would all depend on what Angel needs, which can vary from person to person. Some people like being pulled aside and having their partner ask them grounding questions, while others like to self-soothe and calm themselves down without the help of other people. So, whatever it is that you normally need at that moment, I'm sure Ren would be more than willing to oblige and help out!

For me personally, I don't like having others see me in such an emotional and vulnerable state. If that's the same for you, then Ren would most likely make sure you're somewhere safe before getting rid of the cause of your anxiety attack and waiting patiently for you to come out once you're ready. But if you prefer to have someone around, then Ren would sit by your side, rub soothing patterns into your skin with his thumbs, and ask you to list some of the things you can see/hear/smell.

Again, this answer differs from person to person, so I can't really go into detail or give a specific answer ;v; (aside from like... the bare minimum you'd expect from a person jkgskgk)
