so you are telling us that that $$x\gt -1$$ and $$\ x\le 1$$ or $$-1 \lt x \le 1$$ so you might wish to start out with: $$\large \{ x : \ x\gt -1$$ and $$\ x\le 1 \ \}$$ or $$\large \{ x \in \mathcal{Z} : \ x\gt -1$$ and $$\ x\le 1 \ \}$$ or $$\large \{ x \in \mathcal{R} : \ x\gt -1$$ and $$\ x\le 1 \ \}$$ or $$\large \{ x \in \mathcal{C} : \ x\gt -1$$ and $$\ x\le 1 \ \}$$

but i reckon that the number line is the interesting bit, in the short term!
