The answer is 255. You would use PEMDAS, but when it comes to multiplication and division they work together, so you go left to right like you’re reading a book. It also goes for addition and subtraction.

The value of the expression will be equal to 255.
What is a PEMDAS rule?
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The given expression will be solved by using PEMDAS as below:-
E = 21÷3+(3 x 9) x 9+5
First, solve the numbers in the parenthesis.
E = 21 ÷ 3 + ( 27 x 9) + 5
Again solve the parenthesis.
E = 21 ÷ 3 + 247 + 5
E = 7 + 247 + 5
E = 255
Therefore, the value of the expression will be equal to 255.
