Answer 2

To calculate the expression, follow the order of operations (PEMDAS/BODMAS):

P: Parentheses (Brackets) E: Exponents (Orders) MD: Multiplication and Division (from left to right) AS: Addition and Subtraction (from left to right)

Now, let's solve the expression step-by-step:

18 * 36 - 16 * 36 + 24 * 27 - 25 * 24 - 21 * 5

Step 1: Perform multiplication from left to right.

18 * 36 = 648 16 * 36 = 576 24 * 27 = 648 25 * 24 = 600 21 * 5 = 105

The expression now becomes:

648 - 576 + 648 - 600 - 105

Step 2: Perform subtraction and addition from left to right.

648 - 576 = 72 72 + 648 = 720 720 - 600 = 120 120 - 105 = 15

So, the final result of the expression is 15.
