Let's simplify the expression step by step. 1. Start with the initial numbers: $ 75 + (-120) + (-30) + 75 $. 2. First, combine $ 75 $ and $ (-120) $: \[ 75 - 120 = -45 \] 3. Next, add the result to $ (-30) $: \[ -45 + (-30) = -45 - 30 = -75 \] 4. Finally, add $ 75 $ to the result: \[ -75 + 75 = 0 \] So, the final result of the expression is $ 0 $.

Let's simplify the expression step by step.

Start with the initial numbers: $75 + (- 120) + (- 30) + 75$ .
First, combine $75$ and $(- 120)$ : $75 - 120 = - 45$
Next, add the result to $(- 30)$ : $- 45 + (- 30) = - 45 - 30 = - 75$
Finally, add $75$ to the result: $- 75 + 75 = 0$

So, the final result of the expression is $0$ .
