I wasn't even quite sure what exactly you were asking. But then, good, conformist students spend their time finding out what kind of questions of this type you may ask, what exactly you mean and how to answer. Notice the social control at work: if they are studying, they are not getting into trouble or just enjoying real life. They have to learn early to be good worker drones, and their current job (by the way, unpaid) is to be students. If the Man's agents (educators) deem the answers correct, students advance in their studies and at some point, they are rewarded with a ticket to play the game of seeking employment with the Man. <br /><br />Now that so few people can live off the grid and jobs are harder to get, basically, educators have set up a series of tricky questions between an honest person and that person's paycheck. No wonder many can't do it or do it reluctantly until they get their ticket. When people could simply own a farm or easily become a ditch digger or a housewife, dealing with such abstract nonsense was a choice or a pastime for a small social elite.<br />Monicahttps://www.blogger.com/profile/08103879727877816655noreply@blogger.comtag:blogger.com,1999:blog-491174673971804494.post-55728695147017043632014-10-03T19:58:18.751-07:002014-10-03T19:58:18.751-07:00Well, draw the number line, then put your pencil r...Well, draw the number line, then put your pencil right on "3". By "-2", I mean go "2 to the left of 3". So, start at 3, then go to the left, 2 units...and now you're at "1". So, 3, -2, is 1.<br /><br />And that's how you use a number line to perform subtraction. It's a visual representation of arithmetic. You were probably taught that way when you were 7 years old or so, then internalized it to the point that you don't really think about it that way any more.<br /><br />It's kinda like tying your shoes...you just do it now, but back when you were a little child, it was a complicated process.Doomhttps://www.blogger.com/profile/04528555392898760692noreply@blogger.comtag:blogger.com,1999:blog-491174673971804494.post-73416727518013845032014-10-03T19:18:16.595-07:002014-10-03T19:18:16.595-07:00How exactly do you “Use a number line to determine...How exactly do you “Use a number line to determine the value of 3 – 2”? Just draw a line with a few values like 0, 1, 2, 3 on it, or a full X axis with minus infinity, a few negative values (-3, -2, -1), 0 and a few positive values (0, 1, 2, 3) ending at plus infinity, and then say that 3 is to the right of 2, so the difference is one unit? Or maybe you specify that it's plus one because the values are to the right of 0? The problem is really confusing even though I know that 3 minus 2 equals one. Why even do it with "a number line" when you can just calculate the difference?Monicahttps://www.blogger.com/profile/08103879727877816655noreply@blogger.com
