I am 25 years old today is my 25th birthday so which one is correct well both are absolutely
right today we are gonna talk about numbers in English so let's learn how do we use numbers in
English hey friends welcome back you're with me Niharika and today we are gonna have a look at
numbers in English so am I gonna teach you how to count in English like one two three well not
really I'm gonna teach you the different types of numbers that we have in English and how do we use
them so let's get started now we have two types of numbers one is cardinal numbers and the other one
ordinal numbers so what's the difference well cardinal numbers are used for
few things, of course, they are numbers like 1 2 3 and so on whereas ordinal numbers are
first second third fourth and so on so we're gonna understand when do we use cardinal numbers and
ordinal numbers so let's get started well cardinal numbers are mainly used to count things, in fact,
cardinal numbers are also called as counting numbers so when you have to count something you
end up using cardinal numbers, for example, I have two brothers and three sisters, okay
so I'm counting two brothers and three sisters oh look at these puppies here they are so cute
well i guess there are one two three four five-oh that's a litter of five puppies out there okay
so again you're using cardinal numbers to count something how many books do you have on that table
one two three oh there are three books on that table okay so we use cardinal numbers to count
things so let's say two books five puppies
and so on now we also use cardinal numbers to talk about someone's age I am 25 years old
my brother is 21 years old well my sister is 30 years old
okay so you are using cardinal lumbers to talk about someone's age, so she is 25 years old
Well my dog is 11 years old he's growing old okay, and so on now we also use
cardinal numbers to talk about ears like for example I was born in 1987. my sister was born
in 1990 well my dad was born in 1947 okay, so these are a few examples so when you are
talking about a particular year you use cardinal numbers okay well we went to Australia in 2003
Okay so you use cardinal numbers when you are talking about ears and then the last one is
when you use cardinal numbers is to give your telephone number or when you're talking about
an apartment number or when you're talking about someone's car's number
for example if I ask you hey what's your telephone number oh my number well, it is 247 868
all right so that's just for an example telephone number oh what's your flat number
or what's your apartment number oh I live in 907. so you use cardinal numbers when
you talk about a telephone number an apartment number or a car number my car's number is 4837
okay now let's move on or I'll just put some examples here like a car number,
an apartment number and so on now let's understand when do we use ordinal numbers well ordinal
numbers can be used to talk about date now if you look at the difference here or cardinal numbers
are like one two three but ordinal numbers you have to add like for the one you can say first
for two it's second three it's third and usually you add 'th' to the end of a cardinal number,
so you get like fourth fifth sixth seventh eighth and so on okay so to talk about date let's meet on
the 17th of this month or uh why don't we leave for Australia on the 19th of march okay so when
you are talking about a particular date you use ordinal numbers okay so like 19th of march
and so on we also use ordinal numbers to put things in a sequence okay or to show a rank
so, for example, you know what my daughter came first in the race when I am talking about her
rank, or hey it's going to take long I am still fourth in the queue so again I'm talking about
a sequence I'm fourth in the queue so when you are talking about a sequence, or you're showing a rank
you end up using ordinal numbers so like I'm fourth in the queue or she came first
she came first in the race okay now we also use ordinal lumbers to talk about a floor
in the building like for example my office is on the 10th floor of this building
she has bought a new apartment on the 19th floor of that building okay so when you are
talking about a particular floor you end up using ordinal number so like 19th floor
10th floor and so on but there's a difference
when you are counting the number of floors of a building you end up using cardinal numbers okay
so let's see oh look at this building it looks tall let's count how many floor building it is so
it's like one two three four well it's a ten-story building okay so you end up using cardinal numbers
and then the last one is you use ordinal numbers to talk about birthdays
so, for example, well this is my 25th birthday I'm gonna celebrate my 30th birthday
this Saturday he threw a big birthday bash for on his 40th birthday okay soon you end up using
ordinal numbers when you talk about birthdays, but when you are talking about someone's age
in particular like how old are you I am 25 years old then you use cardinal numbers, but
when you're talking about birthdays it's always ordinal numbers okay so this is my 40th birthday
she celebrated her 21st birthday in vegas
And so on okay so that's the difference, so now next time when you are using numbers in English
you know that there are two types of numbers in English one is cardinal numbers,
and ordinal numbers and then these are the various ways you can use these numbers
so hope you got this clear and I'll be back with a new lesson soon till then you take care,
see you.
