 2    
z  > 0

$$z^{2} > 0$$

z^2 > 0

Rapid solution [src]

And(z > -oo, z < oo, z != 0)

$$z > -\infty \wedge z < \infty \wedge z \neq 0$$

(z > -oo)∧(z < oo)∧(Ne(z, 0))

Rapid solution 2 [src]

(-oo, 0) U (0, oo)

$$t\ in\ \left(-\infty, 0\right) \cup \left(0, \infty\right)$$

t in Union(Interval.open(-oo, 0), Interval.open(0, oo))
