The OR function returns a TRUE if any of its arguments are true and it returns a FALSE if all of
its arguments are false.

The Syntax for the OR function is:
OR(logical1, [logical2], …)

The figure below shows the OR function with three logical conditions. All three of these
conditions are False. If and only if all of the arguments are false will the OR function
return a FALSE.

The first logical condition below is true. The value in cell D1 is less than the
value in cell E1. The other conditions are false. The OR function returns a TRUE because even if
only one logical condition is true the function returns a TRUE.
