[RndTbl] How does on get the date function to work in Libre Office spreadsheet?

[eh at eduardhiebert.com]

Hi,

I've formatted the cells as date mm/dd/yy and entered the values as is. 
Also tried by preceeding with equal sign in case deemed to be a formula 
but neither works.

I assume a difference between two days yields the difference in days, 
correct?  Or are the formula different than plain math?
