What's the meaning of pemdas

PEMDAS is an acronym used in mathematics to remember the order of operations when solving expressions. It stands for:

• Parentheses (or Brackets)
• Exponents (or Orders)
• Multiplication
• Division
• Addition
• Subtraction

This order ensures that everyone gets the same answer when evaluating a mathematical expression, for example, in the expression $3 - 3 \times 6 + 2$, multiplication is performed before subtraction and addition.
