This chapter has been introduced in the syllabus for the students who are preparing for the class 7 examination. At the initial stages, the students might face some difficulties in solving equations involving the decimal number system. But once they understand the concept behind it, solving equations will be easier for them. So, let us learn what the decimal number system signifies.

What is Defined by Decimal Number System?

Decimal is a particular kind of number system and it is one of the standard systems that denote numerical values. Both integer and non-integer numbers can be presented with the help of a decimal number system. To be precise, the decimal number system is used to write or present a particular numerical value that is not whole.


If you are still having issues with understanding the concept, let me clarify it. We write 100 when we want to refer to something that is equivalent to the value of 100. But if the value of the particular thing that you are referring to is something between 100 and 101, then you have to use the decimal number system in order to make the people understand its value accurately. Then you have to write the number like 100.5 or 100.4. 


How to Calculate Decimals?

To calculate an equation involving a decimal number system you must learn how to add or multiply decimal numbers. You also need to learn how to subtract or divide a decimal number with another. But the most basic rule that you need to remember is that you need to be careful during the calculation process and pay special attention, especially while handling the numbers and maintaining the alignment that involves the decimal point.


Do not forget to add the decimal point in the final result that you will be left with, at the end of the calculation process. When you are adding or subtracting, get done with the numbers first that are placed on the right side of the decimal point. Learn the use of the decimal number system and the calculation process involved in it very well as it is one of the basic concepts of mathematics.
