Roman Abbreviations

Classes in Cedar Hill start back tomorrow!  Again, I hope that all students have gotten plenty of rest!

So here's a question to get you thinking.  Anybody can play along!

Before we left for Christmas, a question I posed involved the word MIX as the only English word that is made completely of Roman Numerals.  MIX translates to 1009.  (Thanks for the information, Math-e-magic by Blum, Hart-Davis, Longe, and Niederman, 1997, 1998, 1999, 2000, 2010.) 

So I would like to do the reverse of this.  I'll give you a number that translates to a common abbreviation.  Your job is to figure out what the abbreviation stands for.

     Example:  1500

     Solution:  1500 is MD in Roman Numerals.  What does MD stand for?  Medical Doctor

     The answer is medical doctor.


For my students, I will give extra credit toward this (if completed by Friday, January 7, 2011 at 11:59 PM).  You will get one point for each one you get correct; if you get all five correct, that's 10 points.  The points can be redeemed towards a quiz or test grade in the third six weeks.

For my not-so-afraid friends, I will honor you with recognition and know that the check is in the mail.

Questions:

1.  400
2.  40
3.  101
4.  600
5.  900

You may send a message on my Facebook page or post on this blog.  Good luck!

Answer to "A Question for the New Year"

Did you get it?  Hopefully, it wasn't too hard...

The answer:  Los Angeles is two hours behind Dallas.  So when Los Angeles was at 11:11:11 PM on 12/31/2010, Dallas was at 1:11:11 AM on 1/11/2011.  A way to write the first date of 2011 is 1/11/11.  Which means 1:11:11 AM looks exactly like 1/11/11.

Cool, huh?

A Question for the New Year

I know it has been a while since I've posted here, but hopefully in the new year I will be post more often with mathematical observations and contests.

So here's a question to get you thinking... when the current time in Los Angeles, California is eleven minutes and eleven seconds after eleven in the evening tonight (December 31, 2010), what will be happening at the same time in Dallas, TX?

Answer to appear soon.  HAPPY NEW YEAR!
