1. What is Sum of Series?

The sum of a series is the result of adding all its terms together. In mathematics, a series is the sum of the terms of a sequence of numbers.

2. How Does the Calculator Work?

The calculator uses the basic summation formula:

\[ S = \sum_{k=1}^{n} a_k = a_1 + a_2 + \cdots + a_n \]

Where:

\( S \) — Sum of the series
\( a_k \) — k-th term of the series
\( n \) — Number of terms

Explanation: The calculator splits your input by commas, converts each value to a number, and adds them all together.

3. Importance of Series Summation

Details: Calculating the sum of series is fundamental in mathematics, physics, engineering, and finance. It's used in areas like statistical analysis, signal processing, and financial calculations.

4. Using the Calculator

Tips: Enter numbers separated by commas (e.g., "1, 2, 3.5, -4.2"). The calculator will ignore extra spaces but all values must be valid numbers.

5. Frequently Asked Questions (FAQ)

Q1: What types of numbers can I enter?
A: You can enter integers, decimals, and negative numbers. Scientific notation (like 1.2e3) is also supported.

Q2: What's the maximum number of terms?
A: There's no strict limit, but extremely long lists may cause performance issues.

Q3: How precise are the results?
A: Results are rounded to 4 decimal places for readability while maintaining reasonable precision.

Q4: Can I use this for complex numbers?
A: This calculator only handles real numbers. For complex numbers, you'd need specialized software.

Q5: What if I enter non-numeric values?
A: The calculator will show "Invalid input" if any value cannot be interpreted as a number.
