It's  -1 Day

Or,    Euler's Identity Day,  e^(i*pi)= -1

How do you figure? You haven't identified the field. Neither would be
negative on most modern byte designated architectures nor in most of the
typed languages. Are you a BLISS coder? ;)

And I believe that Euler's Identity is e^(i*Pi) -1 = 0 relating all of
the five fundamental mathematical constants.

It's all relative. The Binary number system has no restrictive fields. Binary can be any length. It's first a mathematical number system, before you ever define a computer system. That's why you don't see leading zeros. You must be a real party pooper ;)

Eh-hem, RTFM
e^(i*Pi) +1 = 0

But in number theory and abstract algebra, you need a field to interpret
your value and or apply any field axioms. So, I guess what I'm trying to
understand is how 11111 and 111111 are equivalent. ;)

Oops. I had typed that and then move the value over so as not to confuse
it being past of the exponental group.

But in number theory and abstract algebra, you need a field to interpret

I think the term "Field Axiom" in number theory can be misconstrued - the word 'Field' doesn't elude to Flip-Flops, thus, octal or hex coding. The origin is called Axioms whenever you postulate when using math.

Twos Complement is not bound to any field, or number coding on whatever system. It's how you implement it in hardware.

The only rule (in shorthand) to get 2's Comp is simply
1. Invert Binary Number

11/1/11: 11111 is 5bit binary math - and it's still -1
11/11/11: 111111 is 6bit binary math - and it's also -1

The two have no logic, digital, or electronic system in common - its just math.

7(dec)+1(dec) is 8(dec)

111(bin)+1(bin) is 1000(bin).

8 or -8???

2's comp is a contrivance and has nothing to do with implementation in
hardware.

So, what you're saying is that if I add enough to 'n' it will eventually
become negative? I don't remember the number line folding back.

When one specifies a size, in this case 5bit >>and<< signed integers (namely 2's comp), your number range is limited from
-(2^(n-1)) to (2^(n-1))-1
Unless of course, you intend to use doubles(or any multiple) - but then it still applies

jeesh, we know who failed Digital 101 now do we ;)
Don't tell me, did you actually build an Full Adder >>and<< Subtractor Logic inside your ALU for class ??

Two's Complement is the main reason you don't need extra hardware for Subtractor logic. You simply use Adder Logic only - even in Multipliers/Dividers. And so became the prevailing dominant method -- among several reasons -- over other signed integer notation, such as, Signed Magnitude, One's Comp, etc  -- beginning in the early 60's.
Even DEC knew that ;)

No shite sherlock but I don't have to treat that addition as producing
a negative. I'm perfectly happy, with my example, to continue counting
to 15 (1111) and then start it all over again. Of course, I'd generate
an OVERFLOW exception or set some overflow flag/status bit but I don't
necessarily have to. And, yes, I do understand digital logic... 1000
is not negative unless I intend to treat it as negative. Hence, it's a
contrivance.
