Answer 2

To solve this expression, we need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction), which tells us to perform the calculations inside the parentheses first, then any multiplication or division, and finally any addition or subtraction.

So, let's start by simplifying what's inside the parentheses:

(6,9+2,55) = 9,45

Now, we can rewrite the expression as:

(9,45) x 2,6 - 3,5 x 2,7

Next, we perform the multiplication and division, starting from left to right:

9,45 x 2,6 = 24,57

3,5 x 2,7 = 9,45

So now our expression becomes:

24,57 - 9,45

Finally, we perform the subtraction:

15,12

Therefore, the result of the expression (6,9+2,55) x 2,6 - 3,5 x 2,7 is 15,12.
