## Surreal Games and Numbers

As many who are into recreational mathematics may have heard about, there is a certain class of numbers which defies all intuition even among those who have worked with the likes of the infinitesimals found in calculus or the transfinite ordinals and cardinals contained within set-theory. These numbers are truly so out of this world they have been called surreals for a reason.

When researching surreal numbers however, a friend wished to know how they are related to games of Hackenbush. Frankly I've always more interested in trying to understand the technical definition of surreals than with some stick-figure game, but putting all hesitancy to the wayside, I will explain how both work to form the marvelous class of numbers John Horton Conway ma…

From Wikipedia:Equivalence relation:

An Equivalence relation is a generalization of the concept of "is equal to". It has the following properites:

• a}} (reflexive property),
• if b}} then a}} (symmetric property), and
• if b}} and c}} then c}} (transitive property).

As a consequence of the reflexive, symmetric, and transitive properties, any equivalence relation provides a partition of the underlying set into disjoint equivalence classes. Two elements of the given set are equivalent to each other if and only if they belong to the same equivalence class.

## Proof that 1+2+3+4+5....... is NOT = -1/12

We can first start out by simplifying adding all previous numbers to the current number.   If you want to solve 1+2+3+4..........+n, an equivalent way to solve this is, (n+1)(n/2).  Examples:  1+2+3 = 4*1.5 = 6, and 3+2+1 = 6.   1+2+3+4 = 5*2 = 10, and 1+2+3+4 = 10.

Now, summing 1+2+3+4+5+6.......+∞ = (∞+1)(∞/2) = w*(∞/2) = w + ((1/2*w)-0.5) ~(approx) w+(w/2).  Therefore, 1+2.........+∞ is NOT = -1/12.

## Successorship

Successorship is adding one to any number.

As an example, n+1.

Adding one is just moving one place to the right on a number line.

n+1 is always equal to n+((1/n)*n)

Some examples:

1.)  (S)3 = 3+1 = 4

2.)  (S)4 = 4+1 = 5

Using repeated successorship will grant you the opportunity to use addition, or just repeated successorship.

## Plex count

The plex count has similar notation as log, but it is right above the exponent.

• 1 Levels
• 1.1 Level 1
• 1.2 Level 3
• 1.3 Level 4

Addition and subtraction take up this space.

Transformation from Level 1-Level 2:

Exponents, roots, logs...

Thansformation from Level 3-Level 4:

7^7^7^7^7^7^7=7th plex 7

Plexes, arc plexes...

The third plex of x is x^x^x^x.

The 4th arc plex of x is the number that you had run through 4th plex to arrive at x.

Ex. 2nd arc plex of 27 is 3.

Please comment below on shortcut math one can use to find arc plexes!

## Clifford algebra

• 1 Rules

Clifford algebra is a type of algebra characterized by the geometric product of scalars, vectors, bivectors, trivectors...etc.

Just as a vector has length so a bivector has area and a trivector has volume.

Just as a vector has direction so a bivector has orientation. In three dimensions a trivector has only one possible orientation and is therefore a pseudoscalar. But in four dimensions a trivector becomes a pseudovector and the quadvector becomes the pseudoscalar.

All the properties of Clifford algebra derive from a few simple rules.

Proof that there is morw irrationals than integers.

Proof:

Suppose you did make a list (assume it is only the irrationals from 0-1). Lets give the first numbers on the list,
1:0.5743857926410654136534629...
2:0.5785605674106541650460134...

4:0.0000000000000000000000000...(After one trillion digits, there is a one)
I can create a number that in not on the list.
The first digit is 0
0.
The next is the first number's 10s on the list +1. (If it is 9, make it a 0.)
0.6
The next is the second number's 100s on the list +1.
0.68
Then, it continues.
0.684167836728460162738462868...
The number is not on the list.

Science is a wonderful thing if one does not have to earn one's living at it. One should earn one's living by work of which one is sure one is capable. Only when we do not have to be accountable to anybody can we find joy in scientific endeavor. -Albert Einstein

It has been known since the time of that all of geometry can be derived from a handful of objects (points, lines...), a few actions on those objects, and a small number of . Every field of science likewise can be reduced to a small set of objects, actions, and rules. Math itself is not a single field but rather a constellation of related fields.

## Symmetry in Mathematics

Symmetry In Mathematics

Symmetry in Mathematics Play A Great Role

If we square 11, it is very simple put 1(2*1)(12)get 121 same as square 12 put 1(2*2)(22) get 144 again for 13 we get 169 and for 14 we get 1 8 16=196 and so on.

When we go deep, we find that there is symmetry of two types

(2,4,6,8,10,12 ,14,16,18,20 …. Diff is always 2) &

(1, 4 , 9 ,16,25,36,49,64,81,100 ) diff. is 3 5 7 9 11 13 15 17 19 and diff. of 3 5 7 9 11 always 2, so there is True Symmetry .

Up to 19 it is right but at 20 how we can put 1 20 100 just because of symmetry.

• 112 = 1 2 1
• 122 = 1 4 4
• 132 = 1 6 9
• 142 = 1 8 16 = 100 + 80 + 16 = 196
• 152 = 1 10 25 = 100 + 100 + 25 = 225
• 162 = 1 12 36 = 100 + 120 + 36 = 256

## Various Research Involving the Floor Function

After reading your article on Rounding, I see that you do not have much information regarding the floor function. I've been working with it on my own for a few years and recently I decided to compile my collective knowledge into one document. I would like to propose that the math wikia add some of the floor function information to the wikia. It's reasonably easy to understand (at least, in my opinion). I know it isn't really filled out too much, but let me know what you all think.

Thanks

## 4D Visualization - Higher Dimensional Space

• 1 Introduction
• 1.1 Higher-Dimensional Space
• 1.2 Why Bother?
• 1.3 Is it possible to visualize 4D?

The world around us exists in 3-dimensional (3D) space. There are 3 pairs of cardinal directions: left and right, forward and backward, and up and down. All other directions are simply combinations of these fundamental directions. Mathematically, these pairs of directions correspond with three coordinate axes, which are conventionally labelled X, Y, and Z, respectively. The arrows in the diagram indicate which directions are considered numerically positive and which are negative. By convention, right is positive X, left is negative X, forward is positive Y, backward is negative Y, and up is positive Z, and down is negative Z. We shall refer to these dir…

## What's the most useful thing you've used Maths for?

For me it's been every time I've completely proved someone wrong in an argument by implementing maths to justify my point. Not a lot of people understand maths to a high to degree so when I use it in an argument it tends to reult in my success. For instance, someone was being a bit christimiatic (hatred of christians) to me and was saying ti's impossible God made everything in the universe. In response I gave him a long mathematical rant of how the probability that this universe exists is so low it may as well be zreo.

What about you? Have you ever owned someone with maths? Have you used it to pull of the most awesome trick? Do you just think it's simply good for finding elegant and beutiful solutions to problems on paper? Post below! :)

## 【1 paradox】Why 0.999... is not equal to 1?

【1 paradox】Why 0.999... is not equal to 1?

Written in 2012

The current mathematic theory tells us, 1>0.9, 1>0.99, 1>0.999, ..., but at last it says 1=0.999..., a negation of itself. So it is totally a paradox, name it as 【1 paradox】. You see this is a mathematic problem at first, actually it is a philosophic problem. Then we can resolve it. Because math is a incomplete theory, only philosophy could be a complete one. The answer is that 0.999... is not equal to 1. Because of these reasons:

1. The infinite world and finite world.

We live in one world but made up of two parts: the infinite part and the finite part. But we develop our mathematic system based on the finite part, because we never entered into the infinite part. Your attention, God i…
