Addition Dot Method

Addition Dot Method Tricks

The process of adding the values of two numbers is called addition. We learn addition in school i.e. adding each column from right to left and carrying the extra’s to the next left side column to get our final answer. Sometime we find difficulty when more than two numbers are to be added.So here in this chapter we are going to learn about addition with Dot Method. Addition -Dot Method is easy, method of adding numbers. First of all let’s understand what this dot method is. In this method we put dot on the left side of the digit and then counted back for the addition for the next column.Suppose here we take 24 + 18 = 72.  4 + 8 makes twelve. Here we write two and take 1 as carry forward. This carry forward 1 is the dot It’s that simple.

Let’s examine this using an illustration now: –

1)   9 + 4 = 13

. 9
+ 4
_______
13

Here we write 3 in answer. And Count

Dot as one. There is nothing to add in

the dot so write dot as one, as it is.

 

2) 6 + 15 = 21

. 6
+ 15

_______

21

6 + 5 = 11 Here we write down 1 and put carry out 1 as

a dot on the left side of digit 6

So dot as one + one is two.

Get answer 21.

Now we have three digits addition example:-

3) 292 + 766 = 1058

. 292

+ 766
__________
1058

2 + 6 = 8, The value 8 thus obtained is less than 10.

Hence, there is no need for a dot

9 + 6 = 15. Here we write down 5 and put carry out 1 as

a dot on the left side digit 2

dot as 1+ 2 + 7 = 10 Here we write down 0 and put

carry out 1 as a dot.

There is nothing to add in the dot ,so write dot as

one, as it is The answer is 1058.

 

4) 392 + 185 = 577

. 392

+ 185
______

577

392 + 185 = 577

2 + 5 = 7. The value 7 thus obtained is less than 10.

Hence, there is no need for a dot

9 + 8 = 17. Here we write down 7 and put carry out 1 as

a dot on the left side digit

dot as 1 + 3 + 1 = 5

The answer is 577.

 

5) 489 + 723 = 1212

. 4.89

+ 723
_______

1212

9 + 3 = 12 Here we write down 2 and put carry out 1 as

a dot on the left side digit

dot as 1+8+2=11 Here we write down 1 and put carry

out 1 as a dot on the left side digit

dot as 1+4+7=12 Here we write down 2 and put carry

out 1 as a dot on the left side digit

There is nothing to add in the dot so write dot as

one, as it is The answer is 1212.

 

6) 1002 + 2338 = 3340

10.02

+ 2338
________

3340

2 + 8 = 10 Here we write down 2 and put carry out 1 as a dot on the left side digit

dot as 1+3=4 The value 4 thus obtained is less than 10.

Hence, there is no need for a dot

0 + 3 = 3 The value 3 thus obtained is less than 10.

Hence, there is no need for a dot

1 + 2 = 3

The answer is 3340.

 

7) 4378 + 2378 = 6756

4.3.78

+ 2378
________

6756

8 + 8 = 16 Here we write down 2 and put carry out 1 as a dot on the left side digit

dot as 1 + 7 + 7 = 15 Here we write down 5 and put

carry out 1 as a dot on the left side digit

dot as 1+3+3=7 Here we write down 7.The value 7

thus obtained is less than 10. Hence, there is no need for a dot

4 + 2 = 6

The answer is 6756.

 

8) 3225 + 105 + 22 = 3352

32.25

+ 105

+ 22
________

3352

5 + 5 = 10 so here we keep 0 in mind put put carry out 1 as a dot on the left side digit , 0 + 2 = 2

dot as 1+2+0+2=5 The value 5 thus obtained is less than 10. Hence, there is no need for a dot

2 + 1 = 3 The value 3 thus obtained is less than 10.

Hence, there is no need for a dot

3

The answer is 3352.

 

9) 1624+ 322 + 72 = 2018

4+2+2 = 8 The value 8 thus obtained is less than 10.

Hence, there is no need for a dot

2 + 2 + 7 = 11 Here we write down 1 and put carry out 1 as

a dot on the left side digit

dot as 1+6+3=10 Here we write down 0 and put carry

out 1 as a dot on the left side digit

dot as 1+1=2

The answer is 2018.

This is the simple way of Addition – Dot Method

By this method we can do any type of additions easily.
