Calculator

Overview

Perform basic arithmetic calculations with step-by-step computation display.

Quick Start

Basic Operations

Addition:

result = 15 + 27
# Result: 42

Subtraction:

result = 100 - 42
# Result: 58

Multiplication:

result = 6 * 7
# Result: 42

Division:

result = 84 / 2
# Result: 42.0

Supported Operations

Operation	Symbol	Example	Result
Addition	+	10 + 5	15
Subtraction	-	10 - 5	5
Multiplication	*	10 * 5	50
Division	/	10 / 5	2.0
Modulo	%	10 % 3	1
Exponent	**	2 ** 8	256

Complex Expressions

Calculate multi-step expressions:

# Order of operations (PEMDAS)
result = (10 + 5) * 2 ** 3 / 4
# Step 1: Parentheses: 10 + 5 = 15
# Step 2: Exponent: 2 ** 3 = 8
# Step 3: Multiplication: 15 * 8 = 120
# Step 4: Division: 120 / 4 = 30.0
# Result: 30.0

Unit Conversions

Temperature

# Celsius to Fahrenheit
celsius = 25
fahrenheit = (celsius * 9/5) + 32
# Result: 77.0°F

# Fahrenheit to Celsius
fahrenheit = 77
celsius = (fahrenheit - 32) * 5/9
# Result: 25.0°C

Length

# Meters to feet
meters = 10
feet = meters * 3.28084
# Result: 32.8084 feet

# Miles to kilometers
miles = 5
kilometers = miles * 1.60934
# Result: 8.0467 km

Tips

• Use parentheses to control order of operations
• Division by zero returns error
• Use

  //

  for integer division
• Use

  %

  for remainder (modulo)
