Parentheses
The symbol of parentheses Is this ( ) and it stands for Please.
Exponents
It is multiplying the number like 3x3x3 which is 27. So the square root for that is 3.
Multiplication and division from left to right
Like I said you do it from left to right like 2x4+(4/2) you do division first then the multiplication.
Addition and Subtraction from left to right
Like I said you do the addition and subtraction from left to right.Just like the multiplication and division from left to right but with addition and subtraction.
