adding decimal calculator

We know that a decimal number is a number with a decimal or a point. This decimal divides the decimal number into two parts , a decimal part & a whole part . While the whole part shows the things in complete , the decimal part shows the same as a part of the whole. Now that we know decimals are numbers & also that we can do any mathematical operation on numbers; so we can add , subtract , multiply or even divide decimal numbers as well .
Let us learn how to add decimal numbers or what is adding decimal calculator.
While learning to add simple numbers, we learnt that each digit of a number has its place & for adding different numbers , the digits of all the addendents must be written at their proper places ; one under the other .
Similarly, we have to do while adding the decimal numbers. In decimal numbers also, each digit has an assigned place & the digits of each number representing a particular place must be written one under the other vertically. By this, we mean that to add decimal numbers, the digits at tens place of each number should be written vertically one under the other & those at ones place & similarly at tenth, at hundredth place & so on for all the places. This would finally result in the decimal of each of the decimal numbers being written in a line, one under the other.
Example : 234.67 + 32.098 + 1875.9 + 5.65
We will write these decimal numbers vertically taking care of the places as follows:
   234.67
     32.098
1875.9
 +    5.650
 2148.318
Thus, the sum is 2148.318

Next blog will be focused on adding and subtracting integers worksheets, algebra problem solver & even Tamilnadu Board Sociology Sample Paper online.
