Answer 2

To calculate the expression:

-405:(36-45:(-5))*3

You should follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right).

Let's break it down step by step:

1. Start with the innermost parentheses: -5 inside the parentheses is a negative number, so we'll make it positive: -5 * (-1) = 5

2. Now, we have the expression without the innermost parentheses: -405:(36-45:5)*3

3. Continue with the division and subtraction inside the parentheses: 36 - 45/5 = 36 - 9 = 27

4. Now the expression becomes: -405:(27)*3

5. Perform the multiplication: -405 / 27 * 3

6. Divide: -15 * 3

7. Finally, perform the multiplication: -45

So, the result of the expression is -45.
