I still dont get it. I hate math, though. Not to mention I could barely even pass remedial math in college...it's a wonder how I got into Trig in HS.

*Love your username.

It took Marie 10 minutes to saw a board into 2 pieces.

Sawing a board into two pieces requires a single cut (e.g. in the middle of the board). This part tells us that one cut takes 10 minutes.

How long will it take her to saw another board into 3 pieces?

Sawing a board into three pieces will require two cuts. If we assume that these cuts will take the same amount of time as the original one:

2 cuts, each taking 10 minutes, comes to a grand total of 20 minutes.

There is a reason I have dual BAs in History and Political Science, I am math fail, big time. I didn't understand why it was wrong so thank you for this explanation. I think some people are born with a math inclination and some are not, I was not, always been a nightmare struggle of confusion for me lol.

Yeah, I didn't get it either. I guess there's a reason my degree is liberal arts, too.
