In Mathematics, there are different types of numbers. Decimal numbers are one among them. The decimal numbers have two parts, namely the whole number part and the fractional part, and these are separated by the point called a decimal point. We can say that the decimals are based on the preceding powers of 10. The decimal numbers can be represented in terms of words and in the expanded form. Like integers, the decimal number can be added, subtracted, multiplied or divided. The addition of decimal number can be performed as follow:

  1. Write down the numbers, such that the decimal point is lined up.
