Calculator with Negative and Positive Buttons

This calculator provides a simple interface with positive and negative buttons for precise numerical adjustments. It's ideal for scenarios where you need to increment or decrement values with quick, intuitive controls.

How to Use This Calculator

Using the calculator with negative and positive buttons is straightforward:

Enter your starting value in the input field
Use the positive button (+) to increase the value by 1
Use the negative button (-) to decrease the value by 1
Click "Calculate" to see the final result

Formula Used

The calculator performs simple addition and subtraction operations based on your button selections. The formula is:

Final Value = Starting Value + (Positive Clicks × 1) - (Negative Clicks × 1)

Where:

Starting Value - The initial number you enter
Positive Clicks - Number of times you click the "+" button
Negative Clicks - Number of times you click the "-" button

Worked Examples

Example 1: Basic Increment

Starting with 10, click the "+" button 3 times:

Final Value = 10 + (3 × 1) - (0 × 1) = 13

Example 2: Combined Operations

Starting with 5, click "+" 2 times and "-" 1 time:

Final Value = 5 + (2 × 1) - (1 × 1) = 6

Example 3: Negative Result

Starting with 3, click "-" 5 times:

Final Value = 3 + (0 × 1) - (5 × 1) = -2
