Answer 2

To solve the expression -1 + 7/19 - 13.6 + 2.97 - (-3 + 7/19) - (-13.6), we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression step by step.

Step 1: Simplify within parentheses

-1 + 7/19 - 13.6 + 2.97 - (-3 + 7/19) - (-13.6) simplifies to: -1 + 7/19 - 13.6 + 2.97 - (-2.89) - (-13.6)

Step 2: Simplify the double negatives

-1 + 7/19 - 13.6 + 2.97 - (-2.89) - (-13.6) simplifies to: -1 + 7/19 - 13.6 + 2.97 + 2.89 - 13.6

Step 3: Perform addition and subtraction from left to right

-1 + 7/19 - 13.6 + 2.97 + 2.89 - 13.6 simplifies to: -1 + 7/19 - 13.6 + 2.97 + 2.89 - 13.6 = -23.45

Therefore, the value of the expression -1 + 7/19 - 13.6 + 2.97 - (-3 + 7/19) - (-13.6) is -23.45.
