I had typos in my response--ignore that earlier version:

in A3:

=a2<a1

(you've got a typo in your explanation ("if A2 is less than A2").

Or
=a2a1
depending on what you really meant.

Or even
=a2=A1
or
=a2<=a1

(what happens when they're equal?)

(I changed all the A3's to A1's in the formulas)

But can u teach me one more thing? I'll really appreciate it.

Example:

I hv three column, Named A1, A2, and, A3.
How can i ask excel to add "false" in A3 if A2 is greater than A1?
And add "True" to A3, if A2 is less than A2
