Basic Calculator Guide & Formulas

🧮 Basic Calculator

Perform fundamental arithmetic operations: addition (+), subtraction (−), multiplication (×), and division (÷). Perfect for everyday calculations, budgeting, and quick math. Features a user-friendly button interface similar to physical calculators.

🔬 Scientific Calculator

Advanced mathematical functions including trigonometry (sin, cos, tan), parentheses for complex expressions, and the constant π (pi). Ideal for students, engineers, and anyone needing advanced mathematical calculations beyond basic arithmetic.

🍰 Fraction Calculator

Add, subtract, multiply, and divide fractions easily. Automatically simplifies results to lowest terms. Essential for cooking measurements, construction projects, and mathematical learning. Handles proper fractions, improper fractions, and mixed numbers.

⚡ Square Root & Powers

Calculate square roots (√), cube roots (∛), and any power (xⁿ). Useful for geometry, physics calculations, engineering formulas, and financial compound interest calculations. Supports decimal exponents for advanced applications.

📐 Fraction Operations

Addition: Find common denominator and add numerators. Subtraction: Similar process with subtraction. Multiplication: Multiply numerators together and denominators together. Division: Multiply by the reciprocal of the second fraction.

🎯 Power Rules

x² means x multiplied by itself. x³ means x multiplied by itself three times. xⁿ means x multiplied by itself n times. Negative exponents create fractions: x⁻² = 1/x². Fractional exponents represent roots: x^(1/2) = √x.
