(EX 145) MIN function A function that displays the minimum value in the range.

(EX 140) TODAY function A date function that displays the current date. (EX 167) trial-and-error method A way to perform what-if analysis by changing one or more of the input values to a value you estimate to see how it impacts the calculated results.
