"SHORT DISCUSSION ABOUT THE PEMDAS"

What is PEMDAS?

→ PEMDAS is an expression for the sequence in which operation must be conducted when evaluating equations containing different operations. PEMDAS, which stands for P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

PEMDAS is a set of rules and regulations that can be used to evaluate mathematical equations. These principles begins with parentheses and go through operations on exponents or powers. From left to right, we execute multiplication and division operations. Lastly, addition and subtraction operations are carried out from left to right.

Things to Keep in Mind:

  • The operations in parentheses should follow first.
  • After that, figure out the exponents in the equation.
  • Take out multiplication or division from left to right, depending comes first.
  • Carry out addition or subtraction from left to right, depending goes first.
