4 When a number is raised to the power of 0, then the value of the number is 1

Gives me a relief when solving stressful math problems involving exponents

6 Trigonometric ratios are easy to solve for

But you can't have a cosecant or cotangent of zero, as it's undefined. - PositronWildhawk

Like sin(0) = 0

7 It is the number of elements in a null set

Null sets make it all easier!

8 It is neither positive nor a negative integer

So no need to remember your signs!

9 In a circle path, the average velocity of an object is 0

This is why physics problems sometimes get easier! What a relief!
