Solution:

The expression provided is:

• \[ 74.7 + (-105.3) - 2 - (-105.3) - 2 - 74.7 \]

Let's break down the calculation step-by-step:

1. Combine like terms: Notice that we have '+ (-105.3)' and '- (-105.3)', which cancel each other out. Similarly, '74.7' and '- 74.7' also cancel each other out.
2. Simplify the expression: After canceling out the terms, the expression becomes:
• \[ -2 - 2 \]
3. Calculate the final result:
• \[ -4 \]
