a. \( (5)+(-4)+(6)+(-1) \) b. \( 3+(-5)+(+4)+(-2) \) c. \( (-0.3)+(-0.5) \)

Calculate the value by following steps: - step0: Calculate: \(\left(-0.3\right)+\left(-0.5\right)\) - step1: Remove the parentheses: \(-0.3-0.5\) - step2: Subtract the numbers: \(-0.8\) Calculate or simplify the expression \( (5)+(-4)+(6)+(-1) \). Calculate the value by following steps: - step0: Calculate: \(5+\left(-4\right)+6+\left(-1\right)\) - step1: Remove the parentheses: \(5-4+6-1\) - step2: Calculate: \(6\) Calculate or simplify the expression \( 3+(-5)+(+4)+(-2) \). Calculate the value by following steps: - step0: Calculate: \(3+\left(-5\right)+4+\left(-2\right)\) - step1: Remove the parentheses: \(3-5+4-2\) - step2: Calculate: \(0\) Here are the results for each of the calculations: a. For the expression \( (5) + (-4) + (6) + (-1) \): \[ 5 - 4 + 6 - 1 = 6 \] b. For the expression \( 3 + (-5) + (+4) + (-2) \): \[ 3 - 5 + 4 - 2 = 0 \] c. For the expression \( (-0.3) + (-0.5) \): \[ -0.3 - 0.5 = -0.8 \quad \text{(or equivalently, } -\frac{4}{5} \text{)} \] Thus, the final results are: - a: \( 6 \) - b: \( 0 \) - c: \( -0.8 \) (or \( -\frac{4}{5} \))
