welcome to another five minutes faster
math class of glad to teach so let's
start this class right way
my question to you is can you mentally
find out and the emphasis on the word
mentally
what is a hundred and four squared in
other words what is hundred four times a
hundred and four you get five seconds
for that and your time starts now you
try i know that you can
your time is up the correct answer would
be 10 eat
16 there it is 108 16
so now let me show you the easy cal
great for finding the squares of the
numbers the fast way
to find the square of hundred and for
the faster way
all you need to do is add this for to
this entire number
so what is 4 plus hundred and four it is
a hundred and eight
so you get the first three digits of
your answer now to more digits to go
so what is the square root of for it is
16 so that's a final answer and thousand
eight hundred and sixteen
hola isn't that simple simple and fast
do you understand what I have done here
ok so let me explain it to you a little
basically what I have done I have taken
the beasts as hundred now hundred and
four is four more than the base so
immediately add that for to this entire
number so 4 plus hundred and four is a
hundred and eight and you get the first
three digits of your answer now since be
a hundred has two zeros so two more tips
to go
so what is the square of four again we
just create that distance square 4 is 16
so the answer is ten thousand eight and
16
so now you find out quickly what is
hundred and seven squared
come on
so once again add this distance from the
base hundred to this entire number 7
plus hundred and seven is a hundred and
fourteen now two more deets to go 7
squared is 49
so the answer is 11,000 449
that's it so what about hundred and
twelve square cannot find it out
so once again add this trail to this
entire number 2 12 plus hundred and
twelve is a hundred and twenty-four now
two more digits to go so well square is
144 the right one here for here and the
other for here now the answer would be
125 for for pastor answer
now don't you think that with this
method
you're not only calculating fast but
easy as well because their next number
of steps involved
now what if the number that we are
trying to squared is below the base that
is below hundred
so how do you think we are going to go
about it
once again the same thing 96 is at the
distance of - 4:00 from hundred isn't it
so subtract that for from 96 96 -
Forrest 92 and you get the first two
digits of your answer
not two more to go what is the square of
this distance four squared is 16 so the
answer is 9216 that's it now you know
that you need not be a mad genius or a
map desert in order to superfast mental
calculations
all you need to know is these simple
tricks are by the way in the next easy
cal trick
you'd be learning the faster way to find
the cubes of the number that is number
multiplied with itself three times like
86 cube it would be a be 6 x 86 x 86
so we'll be learning how to find the
cubes of any number from 1 200 . faster
way and you realize that it is as simple
as finding the squares
