Notes 



Note: take a look at the information about the difficulty levels.

All daily items change at midnight GMT - set your local time zone.

I have deliberately chosen not include the answers - but you could use a calculator to see the value at each stage of the calculation.

Note: BrainBashers has a Dark Mode setting.
