General rules to add decimal numbers:

Step 1: Line up the decimal numbers one by one.

Step 2: Equalize the number of decimal places by adding zeros at the rightmost side of the decimal number.

Step 3: Start adding from the rightmost digit of the decimal number as the usual addition.

Step 4: Add both decimal part and whole number part.

Step 5: Finally, put a decimal point in the answer in the same place as the numbers above it.

Example:

Add \(456.23\) and \(56.026\).

Here, to equalize the decimal places, add zero at the end of \(456.23\).

\begin{array}{l} 456.23 0 \\ \underline{+ 56.026} \\ 512.256 \end{array}

Therefore, the addition of \(456.23\) and \(56.026\) is \(512.256\).

Example:

Find the sum of \(23.592\), \(34.467\) and \(56.83\).

Here, to equalize the decimal places, add zero at the end of \(56.83\).

\begin{array}{l} 23.592 \\ 34.467 \\ \underline{+ 56.83 0} \\ 114.889 \end{array}

Therefore, the sum of \(23.592\), \(34.467\) and \(56.83\) is \(114.889\).
