with d
in this tutorial video you will learn
about the nature of mathematics
mathematics in our world here are our
learning outcomes
the end of this video you must be able
to
identify patterns in nature and
regularities in the world
articulate the importance of mathematics
in your life
argue about the nature of mathematics
what it is
how it is expressed represented and used
and expressed appreciation for
mathematics
as a human endeavor before we proceed to
the content of our discussion
let's have first this illustration and
let's relate it later on
to mathematics as you can see
meron is
has
[Music]
now let's relate it to mathematics
mathematics
proceed let's have this another
illustration
as you can see it is a pattern
tito meron italian two by two
determine a three
or three by three allegri
that's it another
we have this set of patterns
then of course what will be the next
figure here
after triangle we have circle
how about this one of course we all know
the answer
this one next to the inverted triangle
we have
an hexagon
the simplest mathematical objects are
numbers
and the simplest of nature's patterns
are numerical
numbers
the number of petals for the given
flowers here
one metal
one
lima
numbers another example
here is
spiral pattern
of course
spiral pattern
illustration next
is the mathematicians
in the middle europe i see leonardo of
pisa or also known as
fibonacci
at the beginning of a month you are
given a pair of
newborn rabbits so first mind nathan
a pair of newborn rabbits
after a month the rabbits have produced
no offspring
so after a month now guella munna silang
and out however every month thereafter
the pair of rabbits produces another
pair of rabbits
sahai lang sila makahara on an offspring
after another month
the offspring reproduce in exactly the
same manner
if none of the rabbits dies how many
pairs of rabbits will there be at the
start of each succeeding month
let's have this illustration during the
first month of course
there will be no offspring
after the third month
a pair of rabbits will have a pair
of offspring
so there will be two pairs
of new rabbits then
after four months of course there must
be
three pairs of rabbits
the
[Music]
now so after four months man that long
pairs
of rabies how about
after five months yet of course
another beer
so there are five pairs
of rabbits after five months after six
months
same pattern
pairs of rabbits
after eight months
next
okay next
where is mathematics
mathematics practically speaking
it is everywhere
mathematics sample
fingerprints pattern
[Music]
recoveries these are
mathematics
19 it's also mathematics
what is mathematics for
rasa and mathematics first
organized patterns regularities
and irregularities and to predict or
even control
weather epidemics and to provide tools
for
calculations
the total population of the philippines
in 2019 i 106.9
million census
[Music]
total population
item
as you can see there are patterns here
nama pepper dignatin
in the year 2019 here will also
increase
we can use also mathematics to see the
direction of a typhoon
or weather forecast
before mugland fall
next what is mathematics
about of course it is
numbers mathematics is all about
numbers the simplest numbers are those
used
one two three they use their fingers
tweaks stones and objects
that can help them count at present the
set
of counting numbers is also called the
set
of natural numbers take note of that
between 400 and 1280
the concept of zero was invented and
accepted as denoting a
number so in a history book says
that the key idea was the invention of a
symbol for
nothing so zero it represents
nothing the next
extension of the number concept is the
invention of
negative numbers so hanina
one two three four those are the natural
or counting numbers
around time zero and among the invent
u negative numbers negative one negative
two and then etc
when zero negative numbers and the
counting numbers are combined
combination catalonia it is called
integers we also have fractions of
course
positive and negative fractions together
with the integers
fractions as integers are called
rational numbers
numbers the interpreting expressed
into fractions
of nothing irrational example i am
square root number and root of 2i is an
irrational
number rational numbers
and irrational numbers when they are
combined they form a larger number
this larger number is what we call the
set of
real numbers
now the introduction of square roots of
negative numbers and
nothing that it is an imaginary number
it will lead us into complex numbers
so now we have five number systems
so they are the natural numbers
integers rational numbers real numbers
and complex numbers so that means that
mathematics
is all about numbers
its mathematics is only about numbers
mathematics is also about operations at
alumni
four fundamental operations you know
addition
multiplication division subtraction
and in the higher mathematics there is
what we call the binary
operations example two plus
four five
times then so mathematics
is also about operations
mathematics is also about functions
and function is often defined using
algebraic
formulas formulas
and they are functions sample twice
a number okay
two times one becomes two
two times it becomes four
that's function next
mathematics is also a signification of
dignification it is the fact or process
of turning something into
a thing so alumni numbers
i abstract
for example the number four is not a
thing but the process
the number four is turned into thing
when it is associated
two children so that is four children
five cars you know five the old
i abstract parapaksanam i think five
cars
so it's a process of turning something
into
a thing so that's different
signification of
processes and lastly
mathematics also about proof
a proof is an argument a justification
a reason that something is
true it answers the question
why so example y is two plus two
equals two times two
so you have to prove this using
reasoning so that is also
mathematics is all about okay
next how is mathematics done
mathematics is done out of curiosity
and doing mathematics is just like doing
art and nothing has happened i just like
doing
all right
[Music]
mathematics problem
next who uses mathematics
and mathematics of course practically
speaking
everyone uses
so that is all about the nature of
mathematics
thank you for listening and bless you
all
