## Overview

The Sum Calculator is a versatile tool designed to perform rapid mathematical additions, offering advanced features like running totals, grouped sums, and detailed statistical breakdowns for any list of numbers.

## Inputs

- **Numbers Input** (textarea): Enter numbers separated by commas, spaces, or newlines: 10, 25, 30, 45, 20 15 35 40 50
- **Sum Type** (select)
- **Group Size (for grouped sums)** (number): Enter group size (e.g., 2, 3, 5)
- **Decimal Places (0-10)** (range)
- **Show Calculation Breakdown** (checkbox)
- **Show Additional Statistics** (checkbox)

## When to use

- When you need to quickly calculate the total sum of a large list of numbers separated by commas or spaces.
- When analyzing financial or inventory data that requires running totals or cumulative sums.
- When you need to perform specific operations like filtering positive/negative values or calculating grouped sums for batch processing.

## How it works

- Paste your list of numbers into the input field, using commas, spaces, or newlines to separate them.
- Select your preferred calculation mode, such as Total Sum, Running Total, or Grouped Sums, from the dropdown menu.
- Adjust the decimal precision and toggle the breakdown or statistics options to customize your output.
- Click calculate to receive your results instantly, including a detailed breakdown of the operations performed.

## Use cases

- Quickly totaling expenses from a raw list of transaction amounts.
- Generating a running balance sheet from a series of daily deposits and withdrawals.
- Calculating batch totals for inventory items grouped by specific quantities.

## Frequently asked questions
