Summary of my video covering when to use PEMDAS or SADMEP.
• PEMDAS for Simplification and Evaluation: The order of operations, PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction), is used when simplifying or evaluating expressions. This involves working through the operations from left to right in the PEMDAS order. • Inverse Order of Operations (SADMEP) for Solving: When solving equations for a variable (like 'x'), the inverse order of operations (SADMEP - Subtraction, Addition, Division, Multiplication, Exponents, Parentheses) is applied. This means starting with addition and subtraction, then moving to multiplication and division, and so on. • Context Dictates Method: The choice between PEMDAS and SADMEP depends on the problem's goal. Use PEMDAS for simplifying or evaluating expressions, and SADMEP for solving equations to find the value of an unknown variable.
