What is the Order of Operations in Math?

You’ve probably heard that with math equations and expressions, if you do not use the order of operations you might get the incorrect answer.

Do you scratch your head and wonder what are the “Order of Operations” ?

An “operation” in math is a mathematical process.

  • The most common operations are: multiply, divide, add, and subtract.
  • But, there are others such as: exponents (i.e. powers, 
square roots), etc.
