Answer 2

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

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

Let's apply these steps to the expression:

(6.9 + 2.55) · 2.6 - 3.5

Step 1: Parentheses/Brackets Calculate the expression inside the parentheses: 6.9 + 2.55 = 9.45

The expression becomes: 9.45 · 2.6 - 3.5

Step 3: Multiplication and Division (from left to right) Calculate the multiplication: 9.45 · 2.6 = 24.57

The expression becomes: 24.57 - 3.5

Step 4: Addition and Subtraction (from left to right) Calculate the subtraction: 24.57 - 3.5 = 21.07

Final result: 21.07
