Never judge by first glance

So on Friday I sat down to do my math test on logs. Yes, I thought logs belonged in the forest up until about a month ago, and in my opinion they do. There I was, staring at this great big equations with just as many letter as numbers as numbers. I looked at it for a few minutes, thinking to myself that this couldn't possibly make any sense, so I move on, trying to get it out of my head, and do the questions I knew, I knew. I finally get back to it. Roll up my sleeves... Then I realize that every combination of letters and numbers could easily be punched into my lovely calculator. I felt pretty dumb for being intimidated by such a simple thing.
