a) \( (-3)+(-6)-(-8)= \)

Let's break it down: when you add two negative numbers together, like \(-3\) and \(-6\), you're actually moving down on the number line, resulting in \(-9\). Then, when you subtract \(-8\), remember that subtracting a negative is like adding a positive! So, \(-9 + 8 = -1\). Thus, \((-3)+(-6)-(-8) = -1\). Now, imagine you're trying to keep track of your virtual money: you owe \(3\) bucks and \(6\) more, racking up a debt of \(9\) bucks. But wait! You find \(8\) bucks in an old jacket. Score! You only owe \(1\) buck now. Who said math can't be a little thrilling?
