We’ve already covered single digit subtraction in other
workbooks. Let’s review the way subtraction works.
Always remember that subtraction is about taking away.
Let’s say you want to visit a park. When you get to the park you find a
nice patch of flowers. Some lady comes along and picks some of the
flowers.
Start with
a patch of flowers.
Only some
of the flowers
are left.
Some lady picks
some of the flowers.
Sometimes your teachers will have you subtract shapes.
And it’s up to
You are told to subtract you to figure out that
four (4) triangles.
only four (4) are left.
Start with
eight (8)
triangles.
Other times you will practice with a number line.
“If you start with eight (8) and subtract four (4). What value do you have?”

You would be given a starting point of one value. When you are told to subtract,
you skip along the number line to the left.
Usually you will subtract with numbers. You need to subtract when you
see a dash “-” symbol between two numbers. Addition happens when
you see the “+” symbol.

Subtracting single digit numbers from double digit numbers
is no more difficult. You just need to remember that you
subtract ones from ones and tens from tens.
Maybe you’re working on the computer and making small bubbles. You
start with a large group of spheres and then decide there were too
many. You need to subtract a few spheres.
Start with a bunch
of spheres.
Take out a few
of the spheres.
You wind up
with fewer spheres.
It’s all the same even if you are using a whole bunch of shapes.
You are told
to subtract
seven (7)
pentagons.
Start with
eighteen (18)
pentagons.
And it’s up to you
to figure out that only
eleven (11) are left.
It even works the same way with a number line.
“If you start with thirty-eight (38) and subtract four (4). What value do you have?”

When you subtract single digit numbers from double
digit numbers you need to start with the ones and then
move to the tens column.
57
- 4
TENS ONES
57
- 4
Start with
the ones.
57
- 4
3
Then bring the
tens column down.
57
- 4
53
You’re actually doing two subtraction problems. The
first is for the ones column and the second is for the
tens. The tens column subtraction is actually
subtracting zero (0).

the ones.
