Decimal Form

The decimal form shows the result as a standard decimal number, which is useful for quick reference and further calculations.

Fraction Form

The fraction form presents the result as a simplified fraction, which can be more precise for certain calculations, especially when dealing with exact values.

Interpreting Negative Results

Negative results indicate that the calculation produced a value below zero. This is common in scenarios like subtracting a larger number from a smaller one or dealing with negative inputs.

Formula used: The calculator performs basic arithmetic operations (addition, subtraction, multiplication, division) on the input values, converting fractions to decimals as needed.

Practical Examples

Here are some practical examples of how to use the calculator:

Example 1: Adding Negative Numbers

Enter -3 and 5, then select addition. The result will be 2.

Example 2: Dividing Fractions

Example 3: Mixed Operations

Enter -4, then multiply by 3/4. The result will be -3 in decimal form and -3/1 in fraction form.

Remember: The calculator simplifies fractions to their lowest terms for clarity.

Frequently Asked Questions

Can I use this calculator for scientific calculations?

This calculator is designed for basic arithmetic operations with negative numbers and fractions. For more advanced scientific calculations, consider using a dedicated scientific calculator.

How does the negative button work?

The negative button toggles the sign of the current number. Clicking it once changes a positive number to negative, and clicking it again changes it back to positive.

What if I enter an invalid fraction?

The calculator will display an error message if you enter an invalid fraction format. Ensure the fraction is in the correct "a/b" format with a non-zero denominator.
