# Math Examples of Subtracting Whole Numbers

• ## Subtract 357.9 from 543.9?

5    4     3  .  9

- 3     5     7  .  9
--------------------------------
1     8    6     .  0
Step a) Taking first column from right,
9-9=0
Step b)
we have a Decimals in this column, so putting decimal in the answer at the corresponding place.
Step c):
We have, 3 and 7.
3 is less than 7.
So, borrowing from next left column, we have
effects of borrowing,
3 becomes 13.
4 become 3.
13-7=6,
Step d)
we have to subtract 5 from 3 as 4 was changed to 3 in the previous step.
Now, borrowing again as 3 is less than 5.
We have,
13-5=8
Step d) We have, 4-3=1,
5 was changed to 4 in the previous step.

## Subtract 99.2 - 5.5?

Here, we must remember that we have to write Numbers taking digits starting from right to left.
The decimal of both the numbers must be at the right place under same column.
Hence,

9         9       .       2
5       .       5
------------------------------------------
9         3        .        7

Step a) Taking rightmost columns,
2 is less than 5.
So, we have to borrow 1 from the adjacent left column.
Effects of borrowing:
9 become 8.
2 become 12.

Now, subtracting,
12-5=7

Step b) Taking next column, putting decimal in the answer.
Step c) Picking next column,
8-5=3.
We have taken 8 as its value changed due to borrow in the previous step.
Step d)
We have only one element in the last column from the right,
Writing 9 as it is in the answer.

## Subtract  75.2 - 35.1?

7 5  . 2
3 5  . 1
-----------------------
4 0  . 1
Step a):  The decimal subtraction is not different from previous subtraction.
Taking rightmost column from right,
we have two elements,
2 and 1.
2-1=1
Step b) Moving towards left, we have now decimal.
Put the decimal in the answer right below its Position in the question as shown.

Step c): towards left,
We have two Numbers 5 and 5.
So, 5-5 = 0.
Step d) now, we are at the last column from right,
So, the elements are 7 and 5.
7-5=2.
Hence, we have our answer 40.1.

## Subtract the following numbers 5053 and 9365?

In the given Numbers, first we have to decide the greater of the two numbers.
Here, 9365 is greater than 5053.
Now, we can subtract 5053 from 9365 as a lesser number can be subtracted from greater number.

9       3       6      5

5        0       5       3

-----------------------------------
4        3       1        2

Step a) Taking first column from right, we have two elements,
5 and 3.
5-3=2.
Step b): moving towards left,
Taking both elements of the second column from right,
6-5=1
Step c):
now, we have 3 and 0 in the third column from right.
3-0=3
Step d)
Similarly, we have 9 and 5 in the fourth column from right.
Subtracting 5 from 9, we have,
9-5=4.
9365-5053=4312
Till now, we have taken the numbers without Decimals.
Now, consider some examples between the decimal numbers.
Decimal subtraction is similar to the previous subtraction.

## Subtract 755 from 957?

9          5        7
-      7          5        5
_____________________
2           0         2
______________________

Step 1: Taking rightmost column, 7 - 5 = 2.
Step 2: Moving towards left, picking the middle column,
5 - 5 = 0.
Step 3: Similarly, moving towards left and taking the leftmost column,
9 - 7 = 2.
Hence, the answer is 9 5 7 - 7 5 5 = 2 0 2.

## Subtract the given 4 digit numbers 1949 and 455?

1     9      4     9
4      5    5
-----------------------------
1       4      9    4

Step a): Here, we have a 4 digit number and a 3 digit number.
Always keep in mind that we have to write our digits starting from right as shown above.
Taking first column, subtracting 5 from 9,
9-5=4.
Step b): Coming to next column,
we cannot subtract 5 from 4 as 5 is greater than 4.
so, we will borrow 1 from next left column element.
Effect of borrowing:
4 become 14.
9 becomes (9-1) = 8.
Now, we can subtract 5 from 14 as 5 is less than 14.
14-5=9.
Step c): Coming to next column towards left,
8-4=4
Step d) Taking fourth column from right,
we have 1 in the first row but the second number is a 3 digit number.
So, 1 will be unaffected as we have no digit to subtract from it and it is written as it is.

## Subtract the given 2 digits numbers 99 and 55?

9     9
5     5
--------------------
4      4
Step a): Taking first column from right, we have two elements 9 and 5.
Here, 9 is greater than 5. So, there is no need to borrow.
9-5=4,
step b) Now, we have to consider the next column towards left.
We again have the same elements.9 and 5.
9-5=4.
Hence, the answer, 99 - 55 = 44.

## Subtract the following 3 digits numbers 567and 259?

We have done subtraction column wise as follows:

5  6  7
2  5  9
------------
3   0  8
step a ) First, we will take rightmost column and subtract the lower row elements from upper row.
Subtracting 9 from 7, as 7 is less than 9. we cannot subtract it from 9. For this we have to borrow 1 from the left column element.
Hence borrowing 1 from 6, we get
7 becomes 17 and 6 becomes 5.
Now, we can subtract 9 from 17.
Hence, we get  17-9=8.

Step b) Now coming to second column, 6 became 5 in the previous step.
Hence, 5-5=0.
Step c) Now, subtracting third column elements,
5-2=3.
Hence, we get the final answer as 308.

## Subtract the following:                                 5 6 . 9                             -   4 9 . 2                             ___________                             ___________

Step a) Its solution process is similar to all that we discussed above.
Taking rightmost column and subtracting Numbers, we get
9 - 2 = 7
Step b) Coming to the next left column,
we have the decimal digits, so we have to put decimal at the corresponding place.
Step c)
Now, picking the next column towards left,

As 6 is less than 9, hence we have to borrow 1 from adjacent number.
Effects of borrowing:
5 become 4.
6 become 16.
Now, we can subtract,
Hence, 16 - 9 = 7
Step d)
Moving towards left,
We have
4-4 = 0
Remember, 5 became 4 after borrow.
Hence we get our result, which is 56.9 - 49.2 = 07.7.

## What will be the solution of: 3 - 3?

Here we can see that both the Numbers are same, and when we do subtraction of same numbers the result is always zero. Now, we will see how you can subtract this using Column Subtraction, how this process is executed.
3
-3
------
0
------

## What will be the solution of: 3 - 2?

Here we have 3 to left of ‘–‘ while 2 on the right side of it, and as we know that the value of 3 is greater than that of 2, the result will be positive and we have to subtract these single digit Numbers.
3
-2
-------
1
-------
So, we get 1 on subtracting 2 from 3.

## What will be the result of 3 - 7?

Here we can see that the number to the left of “ - ” is smaller than that on the right side of sign so, the result will be have a negative sign, and apart from this we will just subtract 7 by 3 and then put a negative sign in the solution.

7
-3
-------
4
Here we have will change the sign after doing the subtraction, hence we will get “ - 4 “.

## What will be the result of 10 – 2?

Here we have a 2 digit number and a 1 digit number and also the number to the left of ' -' sign is greater than the number to the right, hence the output will be positive.

1 0
- 2
--------
0 8
-------
Here we will first borrow one to make zero at once Position 10 and then subtract 2 from it, placing 8 as output and leaving 0 at ten's place.

## What will be the output of 961 - 23?

Here we have a 3 digit number and we have to subtract a two digit number from it, first we will do the process of subtraction being followed from the one's Position and then moving to the tenth position of that number and in this way we get 938 with a positive sign.

9 6 1
- 2 3
------------
9 3 8
-----------

## What will be the result of 78 - 35?

Here again we have bigger number to the left of '-' sign and we have smaller number to the right of it, giving us positive number, and applying the simple subtraction of first one's and later tenth Position.
We will now see the Graphical representation of this process of subtraction.
7 8
- 3 5
-----------
4 3
------------
Here, we have a simple subtraction and from this we first do the subtraction at one's place and then will move to subtraction at ten's place. Following ( 8 – 5 ) and then ( 7 -3 ) to get the output i.e. 43.
