Abacus Lesson 29 // ADD- COMPOUND Complementary Numbers Respect to 10- TEN'S Column Video Lecture | Abacus Master Class:Become an Expert (English) - Personal Learning

all right this is lesson 29 and we are
doing compound complementary numbers
with respect to the number 10 and 5 in
the tens column now I am assuming if
you're watching this that you survive
less than 28 and that the compound
complementary numbers didn't just
totally overwhelm your brain and it just
gave up and stopped working and I'm
guessing that if you're watching this
you said yeah I can handle that I want
some more
bring it on I want to learn this
advocacy and I am going to do this
whether you like it or not so throw it
at me I can handle it
so I got no other choice we all we all
we can do is just do another round
let's do less than 29 well all right
here we go let's start with the first
one that's 215 plus 26 then 15 plus 26
all right put the number 15 on there
bang there's the number 15 and we are
going to add to that the number 26 now
just like we did before you know where
to start we start on the left hand side
not the right hand side the left hand
side and the first number that we work
with is to the number two in 26 so we
need to add two in the tens column
lots of piece of cake no tricky stuff
here nothing fancy we just go bang we
got two there we move over to the ones
column and we need to add six there
that's where we crack our knuckles and
say all right let's go let's do this all
right
not enough beads we know we need to use
complementary numbers well the
compliment to the number six is the
number four but we got a five involved
so 4 with respect to 5 is
one so slide that out of the way add a 1
and then add one more or carry over a 1
to the next column
there it is 15 plus 26 is 41 hmm that
didn't seem so bad
15 plus 26 to them 41 all right let's do
another one
let's do 58 plus 16 a 5 and 1/8 plus 16
all right so once again we start on the
left hand side over here and we just
need to add a 1 here that's the one in
this of the 16 and we start with that
now we need to add a 6 over here not a
but not enough beads so all right we can
handle that same sequences last time get
5 out of the way add 1 and at carry 1
over into the next column 58 plus 16 is
a 7 and a 474 all right I know you
probably might be sweating a little bit
or something a little bit bead of sweat
on your eyebrow or maybe not
but let's do another one 76 plus 17 a 7
bang and a 676 Plus 17 all right we
start over here we slide one up that's
the one in the 17 and we come over here
to the 7 to add 7 in the ones column
not enough beads the compliment to the
number 7 is 3 and with respect to 5 that
means we're going to go bang bang bang
see that sequence we're doing the same
thing every time and it's going to get
easier I promise
76 plus 17 is
nine and a 376 plus 17 is 93 let's move
on to one just a little bit harder see
if you can handle it we're going to do a
carry over into the hundreds column
let's see how that goes put the number
85 on your abacus at 85 and we are going
to add to that the number 28 and we
start over here on the left hand side
just like we always do let me go here oh
this guy's throwing a curveball at me
you're saying I oh I got to think back a
little bit how do I do that hmm how do I
add two in this column oh yeah
eight and two are complementary numbers
so that means I just get rid of this
eight and add one in the next column
over or I carry one into the next column
over so that made that put a 1 here and
a zero here that's done all right that
means I do an eight in the ones column
and I look at that and say huh yeah this
is the stuff we're doing all right okay
so that the compliment to the number 8
is 2 all right I can handle that
compliment can't take 2 away there's a 5
involved so I think to the compliment of
2 with respect to 5 is 3 so I add 3 take
away that 5 and add carry 1 over into
the next column or add one here and
there's our answer
85 plus 28 is a 1 a 1 and a 3 113 85
plus 28 is 113 all right
was it too bad let's do another you're
just telling me okay
all right you really want to do this
let's do another all right
55 plus 26 there is the number 55 and we
are going to add to that the number 26
all right the first column column on the
left is a piece of cake we just add two
there's the two of 26
now we need to add six in this column
are you looking at me saying that's a
piece of cake I've done that like ten
times already I can do that alright so
all I got to do is that that and that
oops hmm all right that wasn't too bad
five a delay for one and then one and oh
and there's my answer
eighty-one eight and a one fifty-five
plus twenty-six is 81 all right that was
so easy let's just do it let's do
another one see how it goes
all right see féin throwing a curveball
at me that's what you're saying there's
nothing you're probably saying at this
point there's nothing I can throw either
you can't do it well all right try this
one 27 plus 86 so put number 27 on your
abacus and we're going to add to that
the number 86 mmm this looks familiar
well how do I add oh yeah oh I can
handle that
that's not a problem see because I know
the complement to the number two is
eight so while I go I just all I have to
do is just get rid of that two and add
one there see no problem I can handle
that and I just move right on over here
six and I know when I see the number six
when there's a five involved I really
just go like this boom boom ooh I got to
add one here oh there yeah there it is
27 plus 86 is one and one and A three
113 ah all right that wasn't too bad was
familiar to another similar to another
problem that we did all right let's do
one more and I'll see if I can throw a
curve ball yeah let's do 38 plus 96 a
three and an eight
38 plus 96 all right here we are in the
tens column we need to add a nine here
huh all right well I'm not sure what oh
oh yeah I got to think back a little bit
I'm added in this column I need to
subtract the compliment and add one or
carry one over to the next column over
to boom huh all right I remember doing
that that's okay I can handle that made
me stress a little but I can handle that
all right and then we need to add six in
the ones column hmm five involved okay
that means I'm going to be doing this
Bing Bing Bing all right I did it
38 plus 96 is 134 134 boy I can handle
that if you can do that one you can do
any of these all right okay just one one
more and then yeah okay 77 plus 66 Bing
Bing 77 plus 66 all right here we go we
need to add a six in the tens column I
know the sequence I've done it a few
times a six means I go like this being
Bing Bing and then I'm going to add a
six here all right I know that what a
six does it does something like this
Bing Bing Bing huh all right so 77 plus
66 is 143 a 1 of 4 and a 3 is 143 all
right one more then we'll be done with
this lesson okay 36 plus 25 36 plus 25
and I come right here Oh what do I do
oh I need a uh-oh I need to add a 2 here
oh yeah oh yeah I thought he thought he
could throw some curveball at me that's
not a problem look at okay three two or
compliments I know that alright okay so
I go like this
mmm-hmm yeah he thought he could throw
curveball on me but I did that that's
right and a five over here hmm okay oh
yeah oh yeah yeah that's right this
one's a little different there it is 36
plus 25 is 61 so that one actually can
use the compound complementary numbers
just want to see if you can still do
that all right I could I can fill it
these are starting to settle into your
brain and you're feeling like you can
get this so let's just go print off that
worksheet and work through them I don't
think you're all the way there yet but
you're getting close you're getting this
and your brain is starting to wrap
itself around this and becoming
comfortable with the abacus way of
thinking and you're getting there all
right so let's just it there's not an
easy way around it you just have to get
used to doing it stew it over and over
and then maybe maybe you might even want
to take a break for a couple of days or
maybe even a week and then come back and
see if you can do it again well that's
how that's one of the best ways to do is
just to kind of take it works for me
sometimes I take a break and just try
and do something else for a while and
then I come back to it see if I can
still do it and you may want to come
back to this video and watch it again
and see how it goes and refresh your
brain on how to do this
alright so we'll see you in lesson
number 30
you
