36+2• (9• 3): 54- 19

Let's carefully evaluate the expression:

36 + 2 • (9 • 3) : 54 - 19

First, follow the order of operations (PEMDAS/BODMAS):

1. Calculate inside parentheses: 9 • 3 = 27

Now the expression is: 36 + 2 • 27 : 54 - 19

2. Next, handle multiplication and division from left to right:

• 2 • 27 = 54
• 54 : 54 = 1

So, the expression becomes: 36 + 1 - 19

3. Finally, perform addition and subtraction from left to right: 36 + 1 = 37 37 - 19 = 18

Answer: 18
