Google Calculator with Positive and Negative

How to Use Google Calculator with Positive and Negative Numbers

Google Calculator is a built-in feature in Google Search that can perform basic arithmetic operations, including those involving positive and negative numbers. Here's how to use it:

Basic Operations

You can perform standard arithmetic operations with positive and negative numbers:

• Addition: 5 + (-3) = 2
• Subtraction: 5 - (-3) = 8
• Multiplication: 5 * (-3) = -15
• Division: 5 / (-2) = -2.5

Parentheses for Complex Expressions

For more complex expressions, use parentheses to group operations:

• (5 + (-3)) * 2 = 4
• 5 * (-3 + 2) = -5

Exponents and Roots

Google Calculator can handle exponents and roots with negative numbers:

• (-3)^2 = 9
• sqrt(-9) = 3i (imaginary numbers)

Formula and Calculation

The basic arithmetic operations with positive and negative numbers follow standard mathematical rules:

For more complex expressions, the order of operations (PEMDAS/BODMAS) applies:

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (left to right)
4. Addition and Subtraction (left to right)

Worked Examples

Example 1: Simple Addition

Calculate: 7 + (-4)

Solution: 7 + (-4) = 3

Example 2: Complex Expression

Calculate: (5 + (-3)) * 2 + 4 / (-2)

Solution:

1. Parentheses first: (5 + (-3)) = 2
2. Multiplication: 2 * 2 = 4
3. Division: 4 / (-2) = -2
4. Addition: 4 + (-2) = 2

Final result: 2

Example 3: Exponents

Calculate: (-2)^3

Solution: (-2) * (-2) * (-2) = -8
