What Is So Special About X, Y ,Z In Mathematics? by arinzos(m): 11:26pm On Apr 26, 2020
I have Noticed that in Mathematics, Any problem comes with either Looking for X, Solve for X, Dy/Dx, solve for X, Y and Z

What Happened to other Alphabets?
Is there anything special about X, Y and Z
Especially "X"

They are variables it can be any letter anyway

Other alphabets are used o... X Y Z are used mostly in basic equations... Some crazy more advanced math problems dey exhaust all the consonants sef.

Like the Guru above me rightly said, they're just variables often used to indicate an unknown value.

It could be symbols self, but the guy who invented the use of letters didn't have an Android phone, if not e for use smileys. (joking)

Yes X and Y are special because they can't be confused as numbers
Let's imagine this.

q,a and p can be seen as 9
b, h and g can be seen as 6
c, m,n and o can be seen as zero
f and t can be seen as 7
I, l and j can be seen as 1
S can be seen as 8
Z can be seen as 2

George Boole , (born November 2, 1815, Lincoln,
Lincolnshire , England—died December 8, 1864,
Ballintemple, County Cork , Ireland), English
mathematician who helped establish modern
symbolic logic and whose algebra of logic, now
called Boolean algebra, is basic to the design of
digital computer circuits.

Boole was given his first lessons in mathematics by
his father, a tradesman, who also taught him to
make optical instruments. Aside from his father’s
help and a few years at local schools, however,
Boole was self-taught in mathematics. When his
father’s business declined, George had to work to
support the family. From the age of 16 he taught in
village schools in the West Riding of Yorkshire, and
he opened his own school in Lincoln when he was
20. During scant leisure time he read mathematics
journals in the Lincoln’s Mechanics Institute. There
he also read Isaac Newton ’s Principia, Pierre-Simon
Laplace ’s Traité de mécanique céleste , and Joseph-
Louis Lagrange ’s Mécanique analytique and began
to solve advanced problems in algebra.
Boole submitted a stream of original papers to the
new Cambridge Mathematical Journal, beginning in
1839 with his “Researches on the Theory of
Analytical Transformations.” These papers were on
differential equations and the algebraic problem of
linear transformation , emphasizing the concept of
invariance. In 1844, in an important paper in the
Philosophical Transactions of the Royal Society for
which he was awarded the Royal Society ’s first gold
medal for mathematics, he discussed how methods
of algebra and calculus might be combined. Boole
soon saw that his algebra could also be applied in
logic.
Developing novel ideas on logical method and
confident in the symbolic reasoning he had derived
from his mathematical investigations, he published
in 1847 a pamphlet, “Mathematical Analysis of
Logic,” in which he argued persuasively that logic
should be allied with mathematics, not philosophy .
He won the admiration of the English logician
Augustus De Morgan , who published Formal Logic
the same year. On the basis of his publications,
Boole in 1849 was appointed professor of
mathematics at Queen’s College , County Cork, even
though he had no university degree. In 1854 he
published An Investigation into the Laws of Thought,
on Which Are Founded the Mathematical Theories of
Logic and Probabilities , which he regarded as a
mature statement of his ideas. The next year he
married Mary Everest, niece of Sir George Everest ,
for whom the mountain is named. The Booles had
five daughters.

One of the first Englishmen to write on logic, Boole
pointed out the analogy between algebraic symbols
and those that can represent logical forms and
syllogisms, showing how the symbols of quantity
can be separated from those of operation. With
Boole in 1847 and 1854 began the algebra of logic,
or what is now called Boolean algebra. Boole’s
original and remarkable general symbolic method
of logical inference, fully stated in Laws of Thought
(1854), enables one, given any propositions
involving any number of terms, to draw conclusions
that are logically contained in the premises . He also
attempted a general method in probabilities, which
would make it possible from the given probabilities
of any system of events to determine the
consequent probability of any other event logically
connected with the given events.
In 1857 Boole was elected a fellow of the Royal
Society. The influential Treatise on Differential
Equations appeared in 1859 and was followed the
next year by its sequel, Treatise on the Calculus of
Finite Differences . Used as textbooks for many
years, these works embody an elaboration of
Boole’s more important discoveries. Boole’s
abstruse reasoning has led to applications of which
he never dreamed: for example, telephone
switching and electronic computers use binary
digits and logical elements that rely on Boolean
logic for their design and operation.

Boole’s use of symbols and connectives allowed for the
simplification of logical expressions , including such important
algebraic identities as: ( X or Y) = (Yor X ); not(not X ) = X ; not
(X and Y ) = (not X ) or (not Y ); etc.
He also developed a novel approach based on a binary system,
processing only two objects (“ yes-no ”, “ true-false”, “ on-off ”, “ zero-
one”). Therefore, if “true” is represented by 1 and “false” is
represented by 0, and two propositions are both true, then it is
possible under Boolean algebra for 1 + 1 to equal 1 ( the “+” is an
alternative representation of the OR operator)
Despite the standing he had won in the academic community by that
time, Boole’s revolutionary ideas were largely criticized or just
ignored, until the American logician Charles Sanders Peirce (among
others) explained and elaborated on them some years after Boole’s
death in 1864.
Almost seventy years later, Claude Shannon made a major
breakthrough in realizing that Boole’s work could form the basis of
mechanisms and processes in the real world, and particularly that
electromechanical relay circuits could be used to solve Boolean
algebra problems. The use of electrical switches to process logic is
the basic concept that underlies all modern electronic digital
computers, and so Boole is regarded in hindsight as a founder of the
field of computer science, and his work led to the development of
applications he could never have imagined.

this is he mathematics of relativity where two points meet at X, understanding this law or thought makes one a "0 or 1"
unlike bubu who dosent know his bearing or location, booles law transformed mathematics and logic.

if nigeria as a county knew the value of Y and Z they would know their X (destination)
