Columns SUBSTRACTION or something

Hi,
I have this worksheet having 2 columns of numbers. I need help from you for getting this 3rd column meeting the following condition:

- all numbers in column B that are NOT in column A

Maybe it is easy, but I don't have a clue how can be done.
Thanks

if you are prepared to do a few steps which wont take long

in C1 put =IF(ISNUMBER(MATCH(B1,A:A,0)),"",B1)
and copy this down column c to the end of column B where you numbers run out

Select column B copy paste special and past as values on top of itsself to loose the formulas

Now just sort column C to loose the blanks

Regards

Dav
