Introduction:

Addition with decimals is a fundamental arithmetic operation used to combine numbers that include decimal parts. This process is similar to adding whole numbers but requires careful alignment of the decimal points.



Understanding Addition with Decimals:



When adding decimal numbers, it's important to align the decimal points.

Each digit after the decimal point represents a fractional part of a whole number.

Steps for Adding Decimals:



Line up the numbers by their decimal points, placing one below the other.

If the numbers have different lengths after the decimal point, add zeros to the end of the shorter one for alignment.

Add each column of digits, starting from the rightmost digit, and move towards the left.

Place the decimal point in the sum directly below the other decimal points.

Example:



To add 3.75 and 2.4:

Write the numbers aligned by the decimal point:

3.75

+2.40



Add each column, starting from the right:

5 + 0 = 5

7 + 4 = 11 (write down 1 and carry over 1)

3 + 2 + 1 (carried over) = 6

The sum is 6.15.

Key Points to Remember:



Aligning the decimal points is crucial for correct addition.

The decimal point in the sum should be in line with the decimal points of the numbers being added.

Practical Applications:



Adding decimals is commonly used in financial calculations, measurements, and in situations requiring precision, like scientific experiments.
