Subtraction.
if you have not already done so.

There, we covered the basics of Subtraction
and a number of examples on Subtracting
single digit numbers.

That knowledge is a prerequisite here.

Here, we deal with two digit numbers.

## Subtraction of two digit numbers

decimal number system
that the successor to 9 is 10.
or the predecessor to 10 is 9.

i.e. 10 - 1 = 9.

As per the procedure given in
Subtraction of single digit numbers
this. subtracting can be described
as, open 10 fingers and close 1
finger and count the remaining
open fingers to get 9.

We also saw in the
decimal number system
that the two digit numbers
range from 10 to 99.
Knowing these numbers in
figures and in words is
a prerequisite here.

### Example 1 :

Find 15 - 2

```
15
2
--
13
--
```
While subtracting, subtract
units' digits ( 5 - 2 ) to
get 3 and put it in units'
place, then, descend 1 in
tens' place as there is
nothing to subtract
in tens' place.

### Example 2 : To generate Subtraction Table

Now, I ask you what is 11 - 2 ?

Solution 1:
the predecessor to 11 is 10
and predecessor to 10 is 9.

So 11 - 2 = 9.

Solution 2 :
Or you can make use of fingers
of feet also to open 11 fingers
and close 2 fingers and
count the remaining open
fingers to get 9.

Solution 3 :
Or We know 11 - 2 = ---
is same as 2 + --- = 11.

Close all fingers. Start counting
after 2 (to which we are adding)
and rise one finger for every count.
By the time you reach the count to 11,
the number of fingers raised is 9.

This procedure is explained in
examples 4 and 5 and exercise 1B

Here is a collection of proven tips,
tools and techniques to turn you into
a super-achiever - even if you've never
thought of yourself as a "gifted" student.

and remember large chunks of information
with the least amount of effort.

If you apply what you read from the above
collection, you can achieve best grades without
giving up your fun, such as TV, surfing the net,
playing video games or going out with friends!

## SUBTRACTION TABLE

You should be able to subtract
one digit number from two digit
numbers 10 to 18

See the table given below.

 - 1 2 3 4 5 6 7 8 9 10 9 8 7 6 5 4 3 2 1 11 9 8 7 6 5 4 3 2 12 9 8 7 6 5 4 3 13 9 8 7 6 5 4 14 9 8 7 6 5 15 9 8 7 6 16 9 8 7 17 9 8 18 9

From the table,
18 - 9 = 9; 17 - 8 = 9; 17 - 9 = 8;
16 - 7 = 9; 16 - 8 = 8; 16 - 9 = 7 etc.

If you are able to remember or
arrive at the values given in
the table, you can do any
subtracting with the procedure,
we are going to see.

### Example 3 : using of Subtraction table

Find 63 - 39 using Subtraction table

Solution :
Write 39 below 63.

```          63
39
--

--
```

First we have to subtract bottom
digit in the units' place from
the upper digit in the units' place.

i.e. we have to subtract
9 from 3. But 9 is bigger than 3.

So, we have to borrow one (one10)
from the digit in tens' place i.e. 6.

Because of this borrowing, 3 in
units' place becomes 13 and 6 in
tens' place becomes 5.

When we borrow 1 from the immediate
left digit, that borrowing makes the
digit in the right place increase by 10.
This is so, because the immediate
left place value is 10 times the
place value of the right.

Now subtract 9 from 13 which gives 4
(See table above.) in the units' place.

In Tens' place, we have to subtract
3 from 5 to get 2.

This process is shown in the
vertical presentation below.

```
65313
39
--
24
--

```

See 3 in the units' place is
striked off to become 13
and 6 in the tens' place is
striked off to become 5.

13 - 9 = 4 is written in the

5 - 3 = 2 is written in the

Thus, 63 - 39 = 24.Ans.

Check :
We know,
minuend - subtrahend = result.
or subtrahend + result = minuend.

We use this idea to check the
accuracy of our Subtracting.

and verify whether it is equal
to minuend or not.

Here, You may add 24 and 39 and check
whether it is equal to 63 or not.

```
24

--
63

```

It is verified to be correct.

## Progressive Learning of Math : Subtraction Table

Recently, I have found a series of math curricula
(Both Hard Copy and Digital Copy) developed by a Lady Teacher
who taught everyone from Pre-K students to doctoral students
and who is a Ph.D. in Mathematics Education.

This series is very different and advantageous
over many of the traditional books available.
These give students tools that other books do not.
Other books just give practice.
These teach students “tricks” and new ways to think.

These build a student’s new knowledge of concepts
from their existing knowledge.
These provide many pages of practice that gradually
increases in difficulty and provide constant review.

These also provide teachers and parents with lessons
on how to work with the child on the concepts.

The series is low to reasonably priced and include

Elementary Math curriculum

and

Algebra Curriculum.
