Formula Explanation for Each Operation

This calculator works on standard mathematical formulas. Below are explanations of each operation:

1. Sum Formula

The sum adds all three variables:

Formula:
A + B + C

Example:
10 + 5 + 2 = 17

2. Sequential Subtraction

This subtracts B and C from A:

Formula:
A – B – C

Example:
20 – 5 – 3 = 12

3. Multiplication Formula

This multiplies all values together:

Formula:
A × B × C

Example:
2 × 3 × 4 = 24

4. Average Formula

Average calculates the central value:

Formula:
(A + B + C) ÷ 3

Example:
(6 + 9 + 12) ÷ 3 = 9

5. Maximum Value

This selects the highest number among the three inputs.

Example:
Max(5, 12, 9) = 12

6. Minimum Value

This selects the lowest number among the three inputs.

Example:
Min(5, 12, 9) = 5
