📚 Introduction to Mathematics and its Branches
This paragraph introduces mathematics as the fundamental tool that has enabled human achievements, especially in recent centuries. It distinguishes between two main branches of mathematics: continuous and discrete. Continuous mathematics is associated with real numbers and the smooth, unbroken progression of phenomena in the world, such as time and planetary movements. Discrete mathematics, on the other hand, deals with distinct, indivisible values like gender, names, and counts, which became increasingly relevant with the advent of digital computers in the latter half of the 20th century. The paragraph sets the stage for an exploration of discrete mathematics and its applications.

mathematics some call it the language of
the universe
others prefer more technical explanation
and say that it expresses the mechanisms
of the universe maths helps us explore
and explain the world within us around
us and beyond us in many ways
maths is the underlying tool the humans
have used to create some of the most
astonishing achievements especially in
the last few hundred years mathematics
has many branches but it can broadly be
classified into continuous maths and
discrete maths continuous mathematics
deals with real numbers between any two
real numbers there are infinitely many
additional real numbers there are no
gaps in the real number line the
continuous maths operates on continuous
mathematics reflects the world around us
which is smooth and continuous like the
progression of time rotation and
revolution of planetary bodies etc
discrete maths deals with sets of items
that can only contain distinct values
that cannot be further subdivided for
example ideas like gender names of
colours number of siblings you have etc
are all discrete values interest in
discrete mathematics increased in the
latter half of the 20th century partly
due to the development of digital
computers computers operate in discrete
steps and store data in discrete bits
the continuous nature of the physical
world is translated into discrete steps
by digitizing it concepts and notations
from discrete mathematics are useful in
studying and describing objects and
problems in branches of computer science
to glimpse the kinds of problems
discrete maths deals with consider for
people
and for chats how many different ways
can these poor people be seated on the
four chairs if you were to manually
write out all possible combinations you
would see that there were 24 ways but
what if you were dealing with larger
numbers for example 10 people and 10
chairs
the answer is 40,320 and good luck if
you want to calculate that manually you
will encounter more riddles like this
when you come across the topics
combinatorics and permutations another
way you can use discrete mathematics is
to find the shortest path between two
locations you have probably used a GPS
navigator or Google Maps to find the
shortest route to your destination if
you wondered how it's done there are
several possible paths that can be taken
from point A to point B how can you find
the shortest path or you might want to
travel from point A to point B but
intend to visit several other points of
interest along the way how can you plan
the most efficient route so that you
travel the least distance you will learn
how to represent maps and solve this
type of problem in the topic graph
theory by now you might have an idea of
what the wonderful world of discrete
maths is all about it's practical and
it's fun welcome to the land of discrete
maths if you fear maths then confront
your fears with the understanding that
discrete maths is a tool to help
understand and solve interesting
problems it can be your greatest friend
