Study Notes

PEMDAS Order of Operations

Parentheses

  • Evaluate expressions inside parentheses first
  • Follow the order of operations inside the parentheses
  • Evaluate expressions from innermost to outermost parentheses

Exponents

  • Evaluate any exponential expressions next (e.g. 2^3)
  • Evaluate from right to left in case of multiple exponents

Multiplication And Division

  • Evaluate multiplication and division operations from left to right
  • In case of multiple operations, perform the one that appears first from left to right

Addition And Subtraction

  • Evaluate addition and subtraction operations from left to right
  • In case of multiple operations, perform the one that appears first from left to right

PEMDAS Order of Operations

Evaluating Expressions

  • Evaluate expressions inside parentheses first, following the order of operations within them
  • Evaluate expressions from innermost to outermost parentheses

Exponents

  • Evaluate exponential expressions next, such as 2^3
  • Evaluate exponents from right to left in case of multiple exponents

Multiplication and Division

  • Evaluate multiplication and division operations from left to right
  • Perform the operation that appears first from left to right in case of multiple operations

Addition and Subtraction

  • Evaluate addition and subtraction operations from left to right
  • Perform the operation that appears first from left to right in case of multiple operations

PEMDAS: Order of Operations

  • PEMDAS is a mnemonic device that helps remember the order of operations in mathematics, standing for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

Order of Operations

  • Evaluate expressions in the following order:
    • Expressions inside Parentheses first
    • Exponents next
    • Multiplication and Division operations from left to right
    • Addition and Subtraction operations from left to right

Exponents

  • Exponents are a shorthand way of writing repeated multiplication
  • Example: 2³ means 2 multiplied by itself 3 times: 2 × 2 × 2
  • Exponents are evaluated after parentheses, but before multiplication, division, addition, or subtraction operations

Parentheses

  • Parentheses group numbers and operations together
  • Evaluate expressions inside parentheses first, following the order of operations within the parentheses
  • Example: 2 × (3 + 4) means to evaluate the expression inside the parentheses first: 2 × 7 = 14
