A Simulacrum Sum is the sum of any TWO variables, values, ratios, words, text, icons, emojis, or any other physical representations, so :
Since the Simulacrum is the sum of two things, Everything is made a simulacrum with everything else, so
The Everything Everything Simulacrum is Everything + Everything
The Unit Simulacrum of Everything is 1 + Everything
The Null Everything Simulacrum is 0 + Everything

The Everything everything Simulacrum

If there are no Specifications, Everything can interact with everything
The Everything everything Simulacrum, or simply
The Everything Simulacrum is:

The Simulacrum Sum of Everything and everything = SimSum(Everything,everything) = Sum ( Everything+ B ) = 
{Possibilities to Observe: Everything, everything, (Everything/everything), (everything/Everything);
Case 1: Everything<= everything, everything >= Everything, (Everything/everything) <= 1, (everything/Everything) >= 1;
Everything ( 1 + 1/(Everything/everything) )  or  everything ( 1 + (Everything/everything) )
Everything ( 1 + (everything/Everything) )  or  everything ( 1 + 1/(everything/Everything) )
Case 2: Everything >= everything, everything <= Everything, (Everything/everything) >= 1, (everything/Everything) <= 1;
Everything ( 1 + 1/(Everything/everything) ) or everything ( 1 + (Everything/everything) )
Everything ( 1 + (everything/Everything) ) or everything ( 1 + 1/(everything/Everything) ) }

Interpretation Matrix: Definitions of Everything and everything and relationships between them. Everything and everything are ratios to their unit definitions. You can construct the ratios of the variables, Everything and everything, which are ratios to their unit definitions. Thus, The Simulacrum is Ratios of Everything to everything.

The Interpretation Matrix makes you examine the definitions of the words and symbols used. What is Everything? What is everything? Is there a difference between Everything and everything other than the capital E? What is the difference between Everything and everything? Is Everything more than everything?

The existence of two word forms of Everything and everything is proof that Everything can be divided into two forms, Everything and everything.
Thus, it can literally be said that Everything can be divided into two parts.
Everything is Dual.

The fact that Everything can be divided into two parts, or Everything is Dual
aligns with, and corresponds to, Equations for Dimensions, in which
All Dimensions are Dual, x^p/2p.
For more on that, see: Dimension Equations.

Everything Simulacrum shows that Everything is a Simulacrum.
Everything in written form, text, drawing, icon, imoji, etc. has a Simulacrum System with it. A Simulacrum System is the combination of at least three Simulacra: The Simulacrum of Everything with everything, The Unit Everything Simulacrum, and the Null Everything Simulacrum.  See each of thes below:
 The Simulacrum of Everything with everything
The Unit Everything Simulacrum
The Null Everything Simulacrum

The Octagon is the symbol for The Simulacrum because the eight sides represent the eight Solutions in the two Cases of The Simulacrum. The lower and upper halves of The Simulacrum represent Case 1 and Case 2, respectively.
The lower four edges are Case 1, A < B, (A/B) < 1
The upper four edges are Case 2, A > B, (A/B) > 1
The equatorial four edges are Case 1 = Case 2, A = B, (A/B) = (B/A) = 1

The Unit Everything Simulacrum

If you make one specification to the Everything Simulacrum, the first specification is that one value equals one. If you specify that one value equals 1, you get the First Specified Form of a Simulacrum. Since one value is a unit (1), the First Specified Form of a Simulacrum is known as The Unit Simulacrum.

The First Specified Form of a Simulacrum (FSFS),
or simply
The Unit Simulacrum is:

The Simulacrum Sum of 1 and A = SimSum(1,A) = Sum ( 1 + A ) =
{Possibilities to Observe: 1, A, (1/A), (A/1);
Case 1: A <= 1, 1 >= A, (A/1) <= 1, (1/A) >= 1;
A ( 1 + 1/(A/1) ) or 1 ( 1 + (A/1) )
A ( 1 + (1/A) ) or 1 ( 1 + 1/(1/A) )
Case 2: A >= 1, 1 <= A, (A/1) >= 1, (1/A) <= 1;
A ( 1 + 1/(A/1) ) or 1 ( 1 + (A/1) )
A ( 1 + (1/A) ) or 1 ( 1 + 1/(1/A) ) }

Interpretation Matrix: Definitions of 1 and A and relationships between them. 1 can be defined as the unit that defines A, making 1+ A The Unit Definition of A, also known as The Unit Simulacrum of A.

Since 1 + A = A + 1, The Unit Simulacrum is also known as The First Increment.
When you add 1 to something you increment that something. 

1 + 1 is the First Increment of 1 
1/1 = 1
1/1 + 1 is the First Increment of 1/1
1/(1+1) = 1/2 is the First Decrement of 1/1

Again, the Octagon is the symbol for The Simulacrum because the eight sides represent the eight Solutions in the two Cases of The Simulacrum. The lower and upper halves of The Simulacrum represent Case 1 and Case 2, respectively.

The simulacrum is a looking Glass to examine everything in a new way.
Construct "Critical Ratios" to Extract information from data.

The Simulacrum System was discovered step-by-step, from analysis of fats and oils using high-tech instruments and techniques (liquid chromatography and mass spectrometry). I constructed Critical Ratios that provided structural information about triglycerides (triacylglycerols) and how they're metabolized by the human body. 

The first step was The Bottom Up Solution.
Then The Updated Bottom Up Solution.
Then The Simulacrum Sytem.
Then Whole PI.
