How to Use This Calculator
To use this calculator:
- Enter the first number in the "First Number" field
- Select the operation you want to perform (+, -, ×, ÷)
- Enter the second number in the "Second Number" field
- Click the "Calculate" button
- View the result and interpretation
The calculator will properly handle positive and negative numbers according to standard arithmetic rules. For example, adding a negative number is the same as subtracting its absolute value.
Formula Explained
The calculator performs basic arithmetic operations with the following formulas:
Where:
- a = First number
- b = Second number
The calculator follows standard mathematical rules for handling positive and negative numbers in each operation.
Worked Examples
Example 1: Adding Positive and Negative Numbers
Calculate 5 + (-3):
- Enter 5 in the first field
- Select "+" operation
- Enter -3 in the second field
- Click Calculate
- Result: 2
Explanation: Adding a negative number is equivalent to subtracting its absolute value. 5 - 3 = 2.
Example 2: Multiplying Positive and Negative Numbers
Calculate 4 × (-2):
- Enter 4 in the first field
- Select "×" operation
- Enter -2 in the second field
- Click Calculate
- Result: -8
Explanation: The product of a positive and negative number is negative. 4 × 2 = 8, but with the negative sign becomes -8.
Interpreting Results
The calculator shows the result of your operation. Remember these key points:

Frequently Asked Questions
What happens when I divide two negative numbers?
When you divide two negative numbers, the result is positive. For example, (-6) ÷ (-2) = 3.
Can I use this calculator for complex numbers?
No, this calculator only handles real numbers with positive and negative values. For complex numbers, you would need a more advanced calculator.
What if I enter a zero in one of the fields?
If you enter zero in the first field, the result will be the negative of the second number for subtraction, or zero for multiplication and division. If you enter zero in the second field for division, you'll get an error message.
