PEMDAS Order of Operations

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

Learn the step-by-step process of evaluating mathematical expressions using the PEMDAS rule. Understand the order of operations and how to apply it to various mathematical problems.
