Abacus Lesson 15 // Simple Subraction (#'s 0-10) ONE'S column // Step by Step // Tutorial Video Lecture | Abacus Master Class:Become an Expert (English) - Personal Learning

all right now we're going to be doing
simple subtraction in the ones column
the ones column right here but this time
we're going to be using the heavenly
beads and the earthly beads not much
harder but a little bit more complicated
you remember that from the addition that
because they just a reminder I know you
know this but the heavenly beads are
worth five and the earthly beads are
worth one so it brings a little bit of a
different different dimension into the
using the abacus because we're used to
counting by ones but counting with fives
and ones it's a little bit a little bit
more difficult but a piece of cake
because you've already done this before
and you already know that when we move
something towards the beam we're
counting it this says five and if we're
going to take away five or subtract five
from this we move it away from the beam
easy is that okay so let's do a problem
let's put the number nine on our abacus
and you know from doing your addition
that the number nine is a 5 plus a 4
this says 9 ok so so let's do that I
believe you know this is a piece of cake
so 9 minus or 9 take away 5 well all I
have to do is take away 5 and what am I
left with on our abacus 1 2 3 4 4 9
minus 5 is 4 let's do another one let's
do the number 8 there's the number 8 on
our our abacus let's do 8 minus 5 you
can do this I know you can do that so 8
minus 5 piece of cake all you have to do
is move one heavenly bead and we've done
8 minus 5 and what's left 1 2 3
3 8 minus 5 is 3 ok let's do one more
piece of cake one like this put the
number seven on your abacus there is the
number seven and we were going to do is
7 minus 5 maybe you're seeing a pattern
so 7 minus 5 well that means I got to
take away 5 and move it away from the
beam what am I left with is 2 7 minus 5
is 2 piece of cake
all right let's do one that's just a
little bit different so 8 minus 2 put
the number 8 on here again 8 minus 2
well we're subtracting 2 this time and
that those are the earthly beads so I'm
going to slide two of those away 8 minus
2 is what's that number it is the number
6 8 minus 2 is 6 piece of cake let's do
one more of those so well one more of
the ones that are yeah anyways okay
let's put the number mmm let's do the
number 6 there is the number 6 on our
abacus 6 subtract or 6-1 6-1 is well
take away 1 6 minus 1 is 5
it's just a little 5 left up there so 6
minus 5 is 1 all right I think you got
it it's a piece of cake because you know
you've done this before and it's so easy
for you you're like an abacus master
almost well yeah there's some learned
one of course otherwise yeah
so go ahead and print off your worksheet
and work through the problems and with
simple subtraction involving the
heavenly and earthly beads in the ones
column
you
