The calculator supports basic operations including addition, subtraction, multiplication, and division. It also handles negative numbers correctly, ensuring accurate results regardless of the input values.

Formula Used

The calculator uses standard arithmetic formulas for each operation:

Addition: Result = First Number + Second Number

Subtraction: Result = First Number - Second Number

Multiplication: Result = First Number × Second Number

Division: Result = First Number ÷ Second Number

These formulas are applied to both positive and negative numbers, following standard mathematical rules. The calculator ensures that negative signs are handled correctly in all operations.

Worked Examples

Here are some examples of how the calculator handles negative numbers:

Example 1: Addition with Negatives

First Number: -5

Second Number: 3

Operation: Addition

Result: -5 + 3 = -2

Explanation: When you add a negative number to a positive number, the result is the difference between the two numbers, with the sign of the larger absolute value.

Example 2: Subtraction with Negatives

First Number: 10

Second Number: -4

Operation: Subtraction

Result: 10 - (-4) = 14

Explanation: Subtracting a negative number is the same as adding its absolute value. This is known as the "double negative" rule.

Example 3: Multiplication with Negatives

First Number: -2

Second Number: -6

Operation: Multiplication

Result: -2 × -6 = 12

Explanation: The product of two negative numbers is positive. This is a fundamental rule of multiplication with negatives.

Interpreting Results

Understanding the results of calculations involving negative numbers is essential for accurate decision-making. Here are some key points to consider:

Negative Results: A negative result indicates a deficit, loss, or opposite direction compared to the positive counterpart.
Sign Rules: Remember that a negative sign before a number indicates direction or opposition, not necessarily a smaller value.
Absolute Value: The absolute value of a number is its distance from zero on the number line, regardless of direction.
Context Matters: The meaning of a negative result depends on the context of the calculation. For example, a negative profit indicates a loss.

Always consider the context when interpreting negative results. A negative value in one context might be positive in another, so it's important to understand the specific meaning in your situation.
