How to Use This Calculator
Using this calculator is straightforward. Follow these steps to get accurate results:
- Enter the first number in the "First Number" field. You can enter negative numbers by prefixing them with a minus sign (e.g., -5).
- Select the operation you want to perform: addition (+), subtraction (-), multiplication (×), or division (÷).
- Enter the second number in the "Second Number" field. Again, you can enter negative numbers here.
- Click the "Calculate" button to perform the operation.
- View the result in the result panel. The calculator will display the result in its simplest fractional form if applicable.
- Use the "Reset" button to clear all inputs and start a new calculation.
The calculator will handle all operations correctly, including those involving negative numbers and fractions. For example, if you enter -3/4 and 1/2, the calculator will compute the result accurately based on the selected operation.
Formulas and Assumptions
The calculator uses standard arithmetic formulas for each operation:
Where a and b are the numbers entered by the user. The calculator handles negative numbers by applying the standard rules of arithmetic:
- Adding a negative number is equivalent to subtracting its absolute value.
- Subtracting a negative number is equivalent to adding its absolute value.
- Multiplying two negative numbers yields a positive result.
- Dividing two negative numbers yields a positive result.
Fractions are handled by simplifying the result to its lowest terms. For example, 1/2 + 1/3 = 5/6.
Note: The calculator does not perform complex number operations. It handles real numbers only.
