How to remember `a^0=1`  

Anything to the power zero is `1`

A number with the power zero is equal to 1

It doesn't matter how many people there are there is only one sun.

The sun is one? 

One sun is one.


But why?

Try simple numbers you know first

We know `10/10=1` 

But so too `10^2/10^2=1`  

But this can be rewritten as  `10^2\times 10^-2`  

And rewritten again as `10^(2-2)=10^0`

So `10^0` must be `1`
