📐 Formulas

  • Total Sum—S = x₁ + x₂ + x₃ + ... + xₙ
  • Count of Numbers—n = number of values entered

💡 Example

For instance, if you input the values 10, 5, and 15:

10 + 5 + 15 = 30

The total sum is 30.

Real-life examples

  • Monthly Expenses

    If your monthly expenses are $200 for groceries, $150 for utilities, and $50 for entertainment, the total is 200 + 150 + 50 = $400.

  • Project Budget

    For a project, if you have $300 for materials, $150 for labor, and $100 for permits, the total cost is 300 + 150 + 100 = $550.
