Repeated Subtraction: Definition, Diagram, Properties, Examples

Repeated Subtraction: The term Repeated subtraction subtracts an equal number of items from the larger group, also known as division. Suppose the exact number is repeatedly subtracted from the other more significant digit until you get the remainder as zero or a number smaller than the number being removed. In that case, you can write that in the form of division.

What is Subtraction?

Definition: The term subtraction means to reduce the value of one number from another to get the required deal (difference), and the symbol representing subtraction is (-).

Example: \(5\) subtracted from \(10\) we get \(5\) as the answer.

\(10-5=5\) 

If we imagine \(10\) peaches in a basket and take out \(5\) peaches from the basket, how many peaches are left?

The answer is \(5\) peaches.

\(10-5=1+1+1+1+1+1+1+1+1+1-1-1-1-1-1=5\)

Division: The division is the opposite operation of multiplication. It is how one tries to determine how many times a number is contained into another.

The division is also known as the repeated subtraction.

We know that dividing \(20\) by \(5\) means finding the number that multiplied with \(5\) gives us \(20\). Such a number is \(4\).

Therefore, we write \(20 \div 5 = 4\) or, \(\frac{{20}}{5} = 4\) or \(20 – 5 = 15,15 – 5 = 10,10 – 5 = 5,5 – 5 = 0\)

Example: The repeated subtraction sentence is \(36-6=30, 30-6=24, 24-6=18, 18-6=12, 12-6=6, 6-6=0\), now we have subtracted the number \(6\) for \(6\) times division sentence will be \(36÷6=6\).

The repeated subtraction sentence is \(56 – 7 = 49,49 – 7 = 42,42 – 7 = 35,\) \(35 – 7 = 28,28 – 7 = 21,21 – 7 = 14,14 – 7 = 7,7 – 7 = 0\)
now we have subtracted the number \(7\) for \(8\) times, so the division sentence will be \(56÷7=8\).

Division as Repeated Subtraction

Definition: Repeated subtraction of the number is known as division. The mathematical sign denotes the term division consists of a short horizontal line with a dot each above and below the line

Example: The subtraction sentence is \(4-2=2, 2-2=0\), and we have subtracted the number \(2\) for two times, so the division sentence will be \(4÷2\).

The subtraction sentence will be \(15-5=10, 10-5=5, 5-5=0\); we have subtracted the number \(5\) for three times so that the division sentence will be \(15÷3\).

Define Repeated Subtraction

Definition: Subtracting the equal number of items from a more extensive group is known as repeated subtraction, or you can also call it division.

When the exact number is repeatedly subtracted from the other number until you get the remainder as zero or the number smaller than the number removed, you can write that in the form of division.

Example: There are \(25\) balls with a group of \(5\) balls in each group.

In the above image, you can see that the number \(5\) has been repeatedly subtracted \(5\) times. Therefore, you can also write as \(5\) has been deducted \(5\) times from the number \(25\), and you write this subtraction as \(25÷5=5\).

In the same way, to solve any division problem using repeated subtraction, you have to repeatedly subtract the same number again and again until you get the answer. In the given below diagram, you can see there are \(32\) stars. By using the repeated subtraction, you can make small groups of \(4\) stars in each group. You can continuously subtract four stars until you get the answer as zero or more negligible than the number four. 

The repeated subtraction will be \(32-4=28, 28-4=24, 24-4=20,\)
\(20-4=16, 16-4=12, 12-4=8, 8-4=4, 4-4=0\),
so you have subtracted the number \(4\) for \(8\) times, so the division will be \(932÷4=8\).

Facts of Repeated Subtraction

The repeated subtraction can also be helpful for us to learn the division facts like:

1. Repeated subtraction is somewhat like jumping backwards from the more significant number until you get the required answer.

2. You can see the above diagram repeated subtraction on the number line, \(18-6=12→12-6=6→6-6=0\) or \(18÷6=3\).

3. You can even subtract the large numbers in the same way like \(72\), you will write \(72 – 9 = 63,{\rm{ }}63 – 9 = 54,{\rm{ }}54 – 9 = 45,{\rm{ }}45 – 9 = 36,\) \(36 – 9 = 27,{\rm{ }}27 – 9 = 18,{\rm{ }}18 – 9 = 9,{\rm{ }}9 – 9 = 0\) now you have subtracted the number \(9\) for eight times, so the division sentence will be \(72÷9=8\).

Frequently Asked Questions (FAQ) – Repeated Subtraction

Q.1. Explain repeated subtraction with an example.
Ans:
Subtracting the equal number of items from a more extensive group is known as repeated subtraction, or you can also call it division.
When the exact number is repeated subtracted from the other number until you get the remainder as zero or the number smaller than the number removed, you can write that in the form of division.
Example: The repeated subtraction will be \(32 – 4 = 28,{\rm{ }}28 – 4 = 24,{\rm{ }}24 – 4 = 20,\) \(20 – 4 = 16,{\rm{ }}16 – 4 = 12,{\rm{ }}12 – 4 = 8,{\rm{ }}8 – 4 = 4,{\rm{ }}4 – 4 = 0,\) so you have subtracted the number \(4\) for \(8\) times so that the division will be \(32÷4=8\).

Q.2. How can arrays help with repeated subtraction?
Ans:
Array has a fixed number of objects, and all the things are of the same type. It helps to understand the repeated subtraction in a better way without any confusion.

In the above image, you can see that the number \(5\) has been repeatedly subtracted \(5\) times. Therefore, you can also write as \(5\) has been deducted \(5\) times from the number \(25\), and you write this subtraction as \(25÷5=5\).

Q.3. How do you find the quotient by repeated subtraction?
Ans:
When you solve any problem using repeated subtraction, you learn to find out the quotient and the remainder. 
For example, \(42-6=36, 36-6=30, 30-6=24, 24-6=18, 18-6=12, 12-6=6, 6-6=0\), now you subtracted the number \(6\) for seven times division sentence will be \(42÷6=7\), where zero is the remainder, and the number \(7\) is the quotient.

Q.4. Is division similar to subtraction?
Ans:
The term division is related to multiplication in the same way subtraction is related to addition. Removal is related to but not precisely like addition; the repeated subtraction can calculate division in such a way that is related to the way multiplication can be calculated by repeated addition.

Q.5. What is a repeated subtraction example?
Ans:
Subtracting the equal number of items from a more extensive group is known as repeated subtraction, or you can also call it division.
Example: You will write the repeated subtraction sentence as \(45-9=36, 36-9=27, 27-9=18, 18-9=9, 9-9=0\), now you have subtracted the number \(9\) for five times, so the division sentence will be \(45÷9=5\). You can even subtract the large numbers in the same way as \(72\). You will write \(72 – 9 = 63,{\rm{ }}63 – 9 = 54,{\rm{ }}54 – 9 = 45,{\rm{ }}45 – 9 = 36,\) \(36 – 9 = 27,{\rm{ }}27 – 9 = 18,{\rm{ }}18 – 9 = 9,{\rm{ }}9 – 9 = 0,\) now you have subtracted the number \(9\) for eight times, so the division sentence will be \(72÷9=8\).

Repeated Subtraction - Definition with Examples

What is Repeated Subtraction?

Repeated subtraction is a method of subtracting the equal number of items from a larger group. It is also known as division.

If the same number is repeatedly subtracted from another larger number until the remainder is zero or a number smaller than the number being subtracted, we can write that in the form of division.

For example:

If there are 25 balls and we form a group of 5 balls each.

repeated subtraction

Here, the number 5 has been repeatedly subtracted 5 times. We can say that the number 5 has been subtracted 5 times from 25. So, we can write this subtraction as 25 ÷ 5 = 5.

Similarly, to solve a division problem through repeated subtraction, we repetitively group and subtract the same number again and again to find the answer. 

Here are a few examples of repeated subtraction. 

There are 34 stars. How many groups of 4 stars in each can be formed? 

subtraction with stars

In the given image we can see 34 stars. Now, using repeated subtraction, we can group them in smaller groups of 4 stars in each group. We can start to subtract 4 stars repeatedly until we are left with 0 or a number less than 4.

 

      34 - 4 = 30     30 - 4 = 26   26 - 4 = 22    22 - 4 = 18  18 - 4 = 14   14 - 4 = 10  10 - 4 = 6    6 - 4 = 2

We get 8 groups of 4 and with 2 stars remaining.

This example can be mathematically written as 34 ÷ 4. Where 34 is the dividend. The divisor is the number of stars in each group, that is, 4. The number of times 4 is subtracted is the quotient. So, 8 is the quotient and the leftover stars are the remainder. So, 2 is the remainder.

Since repeated subtraction is division, it can be written in 2 ways.

Example: Let’s say there are 18 items. These can be written in 2 ways as shown.

18 ÷ 618 ÷ 3

divisor

When the divisor is 6, we make groups of 6.

We get, 3 groups of 6.

So, 18 ÷ 6 = 3

When the divisor is 3, we make groups of 3.

We get, 6 groups of 3.

So, 18 ÷ 3 = 6

 

Fun fact:

  • Repeated subtraction is like jumping back from the bigger number until you get a zero or a smaller number.

 

repeated subtraction bigger number

18 – 6 = 12       →          12 – 6 = 6         →      6 – 6 = 0

                                             or

                                     18 ÷ 6 = 3

Is repeated subtraction what

Division as Repeated Subtraction

This is a complete lesson with teaching and exercises, showing how division can be seen as repeated subtraction. It is meant for third grade.

Students solve divisions by "subtracting" or crossing out equal-size groups from the total in the visual model, until there is nothing left. Examples show how divisions can be solved by repeatedly subtracting the same number (the divisor). Often, it is actually easier to add intead of subtract, and figure out how many times you will add the number (divisor) until you reach the dividend.

The lesson also shows how number-line jumps tie in with this concept: we jump backwards from the dividend, making jumps of same size (the size being the divisor), until we reach zero. The lesson also has several word problems to solve.



MULTIPLICATION has to do with many groups of the same size.

Here is one group of four. Draw another group of four to the picture.
And another group. And another. And one more group.

 

You drew _____ groups of four.   5 × 4 = 4 + 4 + 4 + 4 + 4 = 20.

Let's reverse the process.  Start out with 20 sticks.

Make one group of four. In your mind, “move it away” from the picture. Form another group of four. Again, “move it away”, or subtract it from the picture.

Keep forming groups of four till you have none left. 
How many groups did you make?  ______

| | | | | | | |
| | | | | | | |
| | | | 

20 − 4 − 4 − 4 − 4 − 4 = 0

This is repeated subtraction.  You subtract 4 repeatedly till you reach zero. 
Each subtraction is a group of 4.
  
How many groups? _____  How many times did you subtract? _____
That is the answer to the division problem 20 ÷ 4. 

1. Make groups, but in your mind 'move them away' or subtract. Write a subtraction sentence. 



DIVISION can be solved by repeated subtraction:

20 ÷ 4 = ??

 

20 − 4 − 4 − 4 − 4 − 4 = 0.
I subtracted 4 five times,
so 20 ÷ 4 = 5.

75 ÷ 25 = ??

I subtracted 21 four times,
 so 84 ÷ 21 = 4

Often, it is handier to actually add instead of subtract:

Since 13 + 13 = 26,
13 goes into 26 two times. So, 26 ÷ 13 = 2

Since 25 + 25 + 25 = 75, 
25 goes into 75 three times. So, 75 ÷ 25 = 3

Since 21 + 21 + 21 + 21 = 84, 
21 goes into 84 four times.
So 84 ÷ 21 = 4

2. Write a multiplication sentence AND a division sentence that fits the addition/subtraction facts.

a.
5 + 5 + 5 = 15

15 − 5 − 5 − 5 = 0

___ × ___ = ______

_____ ÷ ___ = ____

___ × ___ = ______

___ ÷ ___ = ___

d.
14 + 14 + 14 + 14 + 14 = ___

____ − 14 − 14 − 14 − 14 − 14 = 0

___ × ___ = ______

___ ÷ ___ = ___

3. Write a subtraction sentence for each division sentence.

a.  45 ÷ 15 = _______

45 − 

b.  32 ÷ 8 = _______

32 − 

c.  100 ÷ 20 = _______

d.  50 ÷ 10 = _______

50 − 

e.  50 ÷ 25= _______

50 − 

f.  78 ÷ 26 = _______

78 − 

 

Multiplication is like jumps on the number line.

 

5 × 4 =  20.  Five jumps of 4 gets you to 20.

Division is like making jumps of four backwards from 20 till you get to 0:

 

20 ÷ 4 = 5.    20 − 4 − 4 − 4 − 4 − 4 = 0

Five jumps of 4 gets you from 20 till 0.
