## Get busy this weekend, with OR XOR AND [Excel Homework]

Published on Jul 29, 2011 in Excel Challenges, Excel Howtos

Some of you have heard my neighbor’s dog bark in a video or two that I recorded. While I was busy explaining how to do something awesome in Excel, this dog would decide to bark, adding her own two cents to the lesson. Quite a few of my VBA class students have grown used to it. So much that they complain when a lesson doesn’t have a couple of woofs. But I digress.

So coming back, one of the dogs (probably stray) has decided that she should bring her infant puppies and hide them under our terrace stair case. So, now we have 2 cute little puppies barking day long (and very late in to the night) just outside my office window. We have tried hard to get rid of them, but they somehow sneak back in and start barking or crying. So, I will be busy this weekend trying to move them out.

But that doesn’t mean, you have to live Excel-less for a few days. So I have a homework.

### OR XOR AND, Get busy this weekend!

Don’t worry. I am not speaking elvish or something. OR, XOR & AND stand for bit-wise operations. This week, your task is to write formulas in Excel that would get the bit-wise results for AND, OR & XOR.
