Note on Uneven Numbers

Introduction

There are two parts for a decimal number.

· The whole number part

· The decimal part

The whole number part: The digits to the left of the decimal point represent the whole number portion of a decimal number.

The decimal part: The digits to the right of the decimal point represent the decimal part.

Expanded form of a decimal number:

A decimal number can be written as the sum of its whole number part and its decimal place values.

Uneven numbers

If two decimal numbers do not have same number of digits towards right of the decimal point, then the decimal numbers are said to be uneven numbers.

Examples:

11.234 and 1.6 are uneven numbers as both the decimal numbers do not have same number of digits to the right of the decimal point.

Addition of uneven numbers

We have the following steps to add two uneven numbers:

Step1: Make same number of digits after the decimal point by putting 0’s at the right end of the decimal number which has less number of digits.

Step 2: Write the two decimal numbers one below the other keeping the decimal points lined up.

Step 3: Start addition from the right end, such that we add the digits at the same place together. This is similar to addition of whole numbers
