Formula Used

Basic Arithmetic Operations

The calculator performs the following operations based on your selection:

Addition: a + b
Subtraction: a - b
Multiplication: a × b
Division: a ÷ b

Where a and b are the numbers you input, which can be positive, negative, or fractional.

Fraction Handling

When you input fractions (e.g., 1/2), the calculator converts them to decimal form for computation and then presents the result in both fractional and decimal forms when possible.

Worked Examples

Example 1: Adding Fractions

Let's add 1/2 and 3/4:

Convert fractions to decimals: 1/2 = 0.5, 3/4 = 0.75
Perform addition: 0.5 + 0.75 = 1.25
Convert result back to fraction: 1.25 = 5/4

The calculator will display the result as 1.25 (5/4).

Example 2: Subtracting Negative Numbers

Let's subtract -3 from -5:

Perform subtraction: -5 - (-3) = -5 + 3 = -2

The calculator will display the result as -2.
