We can not imagine the subject Math without the term "Decimal". Because, we solve many problems with it. So, we must be aware of adding and subtracting decimals.

To know about how to add or subtract decimals, let us look into the following stuff.

Adding decimals

Let us see, how to add the decimals 0.24 and 0.15.

Observe the figure given below.

0.24 and 0.15 are shaded in two different colors. Now the sum of 0.24 and 0.15 is 0.39

That is,

3 tenths and 9 hundredths

Method 1 :

Therefore, 

0.24 + 0.15  =  0.39

Method 2 :

Not asaaaaaaaaaaaaaaaaa0 . 2 4 aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa+  0 . 1 5  aaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------aaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaa0 . 3 9  aaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------

Therefore, 

0.24 + 0.15  =  0.39 

Note :

In both the methods, arrange the decimal numbers according to the place values and add them.  

Add : 0.75 and 0.5

Not asaaaaaaaaaaaaaaaaa0 . 7 5 aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa+  0 . 2 0  aaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------aaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaa0 . 9 5  aaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------

In the above addition of decimals, 0.2 is taken as 0.20, as the first decimal number has two digits on the right side of the decimal point. 

Subtracting decimals

Let us see, how to subtract 0.14 from 0.25

Method 1 :

Therefore, 

0.25 - 0.14  =  0.11

Method 2 :

Not asaaaaaaaaaaaaaaaaa0 . 2 5 aaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-  0 . 1 4  aaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------aaaaaaaaaaaaaaaaaaaa   aaaaaaaaaaaaaaaaaaaaaaa0 . 1 1  aaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaa-----------

Therefore, 

0.25 - 0.14  =  0.11

Note :

In both the methods, arrange the decimal numbers according to the place values and subtract them.
