Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS) which stands for Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right):

Step 1: Resolve the expressions inside parentheses: 20 - 23,1 * (5 + 7/20 - 4 + 6/35)

Step 2: Perform the operations inside parentheses: 20 - 23,1 * (5 + 7/20 - 4 + 6/35) = 20 - 23,1 * (5 + 0.35 - 4 + 0.17142857)

Step 3: Perform the additions and subtractions inside the parentheses: 20 - 23,1 * (5 + 0.35 - 4 + 0.17142857) = 20 - 23,1 * (1.52142857)

Step 4: Perform the multiplication: 20 - 23,1 * (1.52142857) = 20 - 35.05857143

Step 5: Perform the final subtraction: 20 - 35.05857143 = -15.05857143

The solution is approximately -15.0586.
