The more technical answer to "what are negative numbers?" which was asked in class is: take the set of ordered pairs of non-negative numbers (so (1, 2) is different from (2, 1)). Then calculate the difference between them, in the above case, the difference is 1. An integer number is the set of all pairs of whole numbers with the same difference. So (5, 3) and (8, 6) are both in the set representing the integer "2". And you can check that addition and such works, regardless of which pair you choose: (5, 3) + (8, 6) = (13, 9) says that 2 + 2 is 4, even though we chose different pairs to represent the number 2. A negative number is just the same thing, but in the case where the second number is larger than the first number. So (5, 3) is part of 2, but (3, 5) is part of -2. And again, you can check. (3, 5) + (8, 6) = (11, 11) says that -2 + 2 = 0. Of course, this is not how anyone actually thinks about negative numbers: the point is that, in mathematics, we always want to avoid contradictions. Checking that this works tells us that, provided there are no contradictions in the positive numbers, a simple structure, then there are no contradictions in the negative numbers, which are more complicated.

I sat in my chair mind blown not knowing if I was peaking from the weed or actually having an epiphany. I thought dividing by 0 would create unmeasurable chaos.

Late to the party, but my 2c: I think you can get a decent amount of math from 4 things: 0, incrementation (adding 1), repetition, and inverse (opposite operation). From 0, repeated incrementation produces addition and the natural numbers. The inverse of addition (or the repetition of the inverse of incrementation) produces subtraction and the negative numbers. Repeated addition produces multiplication. The inverse of multiplication produces division, and the rational numbers. Repeated multiplication produces exponents. The exponential function can be inverted in two different ways to produce the root and logarithm functions, complex numbers, and a more (but not all?) of the real numbers.

I would say that division by zero is undefined due to the definition of division and the definition of zero. Division is to break up or divide a number by another number. Zero is a number that represents nothing. Dividing by zero is to divide by nothing, which is essentially trying to divide by not dividing, since dividing by nothing is the same as not dividing in the first place. Thus, division by zero, by he definitions of division and zero, violates the law of non-contradiction, which is one of the key logic laws that mathematics follows.

I would say that sets breaks down to counting, then comes "Haves and Have-nots." Which can be presented as 1 and 0. Now all are operations stem from counting. So addition use counting of the sets, and subtraction is the opposite but still is counting. Now multiplication is faster adding which goes down to counting. Then once again, division is the opposite but is still counting. If you want you can include any operations, and they will break down to counting then too "Haves and Have-nots." One more example is exponents, which is faster multiplication and it breaks down..... Now the opposite would be roots. This is the whole computer world 0 and 1.

@@daviddemar8749 What I, having been a poor student of the calculus, found most fascinating to learn recently about math was that of the simplest case of quantum mechanics that can be described, the spin on a single electron. Leonard Susskind lays it out it in KZbin posts from Stanford University. Quantum mechanics (QM) is a mathematical procedure that allows to predict the statistical outcome of repeating an experiment on a quantum system many times. When you measure the spin on an electron, there are only two possible results, spin up and spin down. QM says, given the angle you measure it at, the probability that the outcome will be spin up. To understand the math of this simplest case, you do not have to know any of the calculus. Just a little matrix arithmetic and complex numbers, but Susskind explains all that, for an audience who may have forgotten. And the notation used in QM is cool and abbreviates quite a lot with a few symbols. For example, if you see something like |a>, that's pronounced "ket a" and it denotes some column vector i. e. a matrix with just one column. And . Multiply a row by a column and you get a scalar (i. e. a single number).

@@b43xoit Sounds fascinating I'll have to check it out. However I have confess that my understanding of QM doesn't go much beyond knowing about the double slit experiment, schroedinger's cat and knowing about the macro conflict between QM and classical Newtonian physics. This does put me way of the vast majority of the American population and only bc I'm blessed to be an alum ('78) of the Bronx High School of Science .

@@daviddemar8749 Even though that particular series from Susskind is really an elementary introduction to QM, the title indicates that it is about entanglement. And he does eventually get to entanglement.

Events are the basic building block of special relativity. Binary numbers - equivalently, Boolean algebras - constitute the basic building block of mathematics - including logic and category theory (even of non-binary logic)!

An atom is the smallest fragment of a given element. It can not be divided into smaller fragments of the same element. So the word still orks as a definition.

Hey Dr. Woo! I got an idea. Let's make 1 the building block of *all* of arithmetic! We'll make everything else from it with a single operation - perfectly suited for balancing accounts - that we call "take-away", and denote it as "−". Every number, we shall decree, can be formed from 1 by taking combinations of take-away operations with it. We will impose two conditions: (a) for all numbers a, b: a − (a − b) = b, (b) for all numbers a, b, c: a − (b − c) = c − (b − a). We'll *define* the number 0 as 1 − 1 and call it the "break even" number. We'll then *prove* as a theorem that (c) for all numbers a: a − a = 0. Proof: a − a = 1 − (1 − (a − a)) = 1 − (a − (a − 1)) = 1 − 1 = 0, by applying (a), (b), (a) and the definition of 0. We'll *define* the "take-away" of a number as -a = (a − a) − a and use the theorem to prove that 0 − a = -a. Then, we'll define the *sum* of two numbers as a + b = a − -b and ... with these definitions ... prove that we have *all* the basic laws of arithmetic for the operations of plus and minus. For instance, a + 0 = a − -0 = a − (0 − 0) = 0 − (0 − a) = a and 0 + a = 0 − -a = 0 − (0 − a) = a ... using the axioms and results proved up to this point.

What makes up Math? The equilibrium around numbers such as Pi, i, and e. Numbers are units we made up, but in the end it's just a balance of the numbers around equilibrium to come to an answer.
