2)6,8 - 1,9 = 4,9
3)-15,6 + 23,6 =8
4)8- 4,9 =3,1

Answer 2

To solve the expression 23.6 + (14.5 - 30.1) - (6.8 - 1.9), we can follow the order of operations (PEMDAS/BODMAS):

Step 1: Solve the innermost parentheses first. 23.6 + (14.5 - 30.1) - (6.8 - 1.9) = 23.6 + (-15.6) - (4.9) = 23.6 - 15.6 - 4.9

Step 2: Perform subtraction from left to right. = 8 - 4.9

Step 3: Perform addition. = 3.1

Therefore, the result of the expression 23.6 + (14.5 - 30.1) - (6.8 - 1.9) is 3.1.
