Operations

  • Addition (+): Combines two or more numbers
  • Subtraction (-): Finds the difference between numbers
  • Multiplication (×): Finds the product of numbers
  • Division (÷): Divides one number by another
  • Percentage (%): Calculates percentages of numbers
  • Square Root (√): Finds the square root of a number

Mathematical Rules

When performing calculations, remember these important rules:

  1. Order of Operations: PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction
  2. Division by Zero: Undefined in standard arithmetic
  3. Negative Numbers: Follow specific rules for operations
  4. Decimal Precision: May be limited by the calculator's implementation

Basic Arithmetic Properties

Addition & Multiplication

  • Commutative: a + b = b + a and a × b = b × a
  • Associative: (a + b) + c = a + (b + c) and (a × b) × c = a × (b × c)
  • Identity: a + 0 = a and a × 1 = a
  • Distributive: a × (b + c) = (a × b) + (a × c)

Subtraction & Division

  • Not Commutative: a - b ≠ b - a and a ÷ b ≠ b ÷ a
  • Not Associative: (a - b) - c ≠ a - (b - c) and (a ÷ b) ÷ c ≠ a ÷ (b ÷ c)
  • Inverse Operations: Subtraction is inverse of addition; division is inverse of multiplication

Educational Uses

Basic arithmetic calculators serve important educational purposes beyond just computing answers:

  • Concept Verification: Students can check their manual calculations to reinforce understanding
  • Pattern Recognition: Exploring number patterns and relationships by testing multiple calculations
  • Estimation Skills: Using the calculator to verify mental math and estimation skills
  • Problem-Solving: Breaking down complex problems into simpler arithmetic operations
