Divisibility by 10 - Playing with Numbers Video Lecture | Mathematics & Pedagogy Paper 2 for CTET & TET Exams - CTET & State TET

hi so now we are on the divisibility
rule of ten I yes it is very simple as I
think it has the simplest rule among the
divisibility rules it says that the
number at the unit's place should be
zero and what is the table of ten table
of ten is ten was a 10 10 - 20 10 3 30
40 50 60 70 80 and 90 and then we have
100 in all these numbers the unit place
is zero so I think it is the simplest
divisibility rule in which you just have
to see if the unit place has zero or not
and if unit place is zero it is
completely divisible by 10 otherwise the
number at the unit's place will be the
remainder so let's check it and if I
take a number like 237 this number
doesn't have zero at units place right
so it should not be divisible by 10
anyway let's try and check if it is
divisible by 10 or not ten to thirty
three is remainder if we note this 7
town 10 threes are 30 37 minus 30 gives
us seven as remainder this is what I was
talking about if the unit's place is not
zero the number at units place will
become remainder right yes so now let's
take a number which has zero at units
place so let me take 450 it should be
divisible by 10 right so if we divide it
by 10 10 fours or 40 minus 5 minus 0
gives us 5 4 minus 4 is 0
so now let's note the zero down and 10 5
sir 50 50 - 50 gives us zero so here we
have got zero as remainder right
this means 450 is completely divisible
by 10 right so I think it is a simplest
rule and we need not to discuss more
about this we you just have to check if
the unit's place has zero or not so if
you have zero at units place the number
is divisible by 10 right otherwise the
number at units place will be the
remainder okay and the number made from
the digits except the digit at units
place will be the quotient like in this
case we have caught quotient as 23 this
is nothing but this the number made by
the digits other than the digit at units
place similarly here also we have got
quotient as 45 right because the unit's
place has zero and in this case also we
are omitting the number at units place
right so I think it is very simple and
we have discussed lots of fun concepts
over here right so I think this is
sufficient and in next video I am
discussing the divisibility rule of
