Abacus Lesson 12 // Simple Subraction (#'s 0-5 only) ONE'S column // Step by Step // Tutorial Video Lecture | Abacus Master Class:Become an Expert (English) - Personal Learning

the next nine lessons we're going to be
covering subtraction now subtraction
isn't a bit harder that is not not even
a little bit harder than addition it's
just the opposite in math everything has
its opposite and subtraction is the
opposite of addition so if you're a
little bit if you know your math pretty
good the next nine lessons are going to
feel a little bit like a bit of a
digression it's going to feel kind of
repetitive and dumb and so these lessons
are going to be a little bit shorter
well significantly shorter than the
additional addition problems that we had
before and so and that's because you
know the abacus by now you know how to
move your fingers around it's going to
be a lot easier for you and so we're not
going to spend as much time but we do
need to cover the the subtraction and
this is you know because you're an
expert by now you know your addition and
this might seem a little bit too easy
for you but don't worry about it just
kind of go through the lessons if you
feel like you need to skip a part I
guess you can go ahead and skip it but
still I suggest that you work at least
work through the problems on the
worksheet just to get used to it to get
your fingers moving through the motions
and so that you're familiar and you're
not fumbling around with the abacus if
you really want to use it so we're going
almost all the way back to the first
lesson in addition and we're going to
cover just basic subtraction which is
the opposite of addition so you know
when we added something if we you know
right now the abacus says zero because
there's nothing touching the center bar
when we add something we move it towards
the center bar
and now that says one well you probably
guess if I'm going to subtract I'm going
to do just the opposite of that and so
since this says one and if I want to
take away one or subtract one and make
it say zero I move it away from the bar
see that's easy piece of cake addition
subtraction when I add I move it towards
the bar when I subtract I move it away
from the bar
piece of cake I know you can handle that
I probably seems dumb that I'd even say
that but just in case I am seeing it
plus one minus one addition subtraction
add one take away one as easy as that
add to take away 2 add 3 take away 3 add
30 take away 30 add one 1324 and take
away 1 that's how easy is that that's
how we do it so let's start with the
ones here we go let's the first problem
3 minus 1 3 take away 1 however you want
to say it so if I'm going to take 3 if I
have 3 and I want to take away 1 or
subtract 1 then all I do is move that
down and what do I have left - piece of
cake clear the abacus put 2 on there
this is let's do to take away 2 or 2
minus 2 that means I move two beads away
from the center beam and what am I left
with zero an abacus where none of the
beads are touching the center bar reads
0 but of course you know that let's just
do a couple more for 4 take away or
or subtract 4 - however you want to say
it 4-3 is that means I have to take away
3 beads move them away from the center
bar and the answer is 1 4 minus 3 is 1
piece of cake ok clear the abacus let's
do 2 minus 1 well I know you can do this
in your head because you're smart like
that but 2 beads
minus 1 so I take away one of the beads
and one of my left with 1 3 minus 2 take
away 2 beads and all I'm left with is 1
so 3 minus 2 is 1 4 minus 2 4 minus 2 is
2 there's two beads left touching the
center beam so the answer is 2 and
that's it for this lesson that's all
we're going to do I know it's really
easy for you go through the lesson and
just practice a little bit of your
subtraction the important thing to
recognize is that in math there's
opposites and subtraction it's the
opposite of addition so go and print off
your worksheet and work through the
problems and take some time going
through each of them to get your fingers
used to doing subtraction
you
