I get the impression raccoons are very smart/crafty and yes I know it's dark but you think being nocturnal they'd have some kind of night vision!

I know how to combine like terms--it's simple.

I also know that the answer to this riddle is "keyboard."

What I don't know is what it's asking to do.... like, once i combine the like terms for each problem then what? How are the answers from the first column suppose to match the answers to the second column???

And why do they have the problems separated in parenthesis?

If you can do problem A so I can compare mine just to see if I'm doing it right too, that would be great.

Thanks.

The Question has been asked enough times. Those who have spent their professional careers studying the solar system have made their choice. Nothing changes if Pluto is no longer considered a planet. It is right where it has always been (and beyond even viewing by most who are protesting). What is the big deal? Science moves forward. It is ever changing. Few believe that the world is flat or that fire is made from the release of phlogiston. How is Pluto not being a planet changing your life?

I am in Iraq right now and all I can think about is sex, I am 22yrs old and I know it is normal but it is all the time my work has me talking and doing things with women. (old or young) when I see a women I get this feeling it is bothersome it effects my work I do my best to block it out but it isnt working the first glance at a women and it is SEX nothing else that to me is both rude and stupid. Anyone have anything I could do to keep my mind on the mission and not the women. I do watch movies read books and things but I am out of ideas.
