Understanding Decimal Addition

Decimal addition is a fundamental arithmetic operation used to find the sum of two or more decimal numbers. It's an extension of whole number addition, but with the added consideration of the decimal point. When adding decimals, it's crucial to align the decimal points to ensure that you are adding digits with the same place value.

For example, to add 2.5 and 3.75, you align the decimal points and add column by column, starting from the right:

Align the decimal points:
```
   2.50
+  3.75
-------
          
```
Add each column from right to left, carrying over when necessary:
```
   2.50
+  3.75
-------
   6.25
          
```

This calculator simplifies the process for you, handling both positive and negative decimals to quickly find the sum. Enter your decimals separated by commas above to get started!

Formula

The sum of decimals $d_1, d_2, ..., d_n$ is represented as:

$$ Sum = \sum_{i=1}^{n} d_i = d_1 + d_2 + ... + d_n $$
