Want to see if your friends are too drunk on New Year's Eve to think straight? Try this little game I just made up. It might be a good sobriety test! Alternatively, the 2013 Numbers Game might come in handy when driving a long distance with cranky kids. All you need to be able to do is add and subtract.......
THE 2013 NUMBERS GAME (and no, it's not about the "fiscal cliff")
New Year 2013 Trick Questions:
- How many ways can you arrange the numbers in the year "2013" so the numbers go in order?
- Which three numbers can you add so that the sum of the three numbers equals the fourth number, using the numbers in the New Year, "2013?"
- Which numbers in the New Year "2013" can you multiply and get the same number as you do when you add them?
- How many years greater or less than a millennium is the difference between this New Year, "2013" and the reverse of those numbers?
- Two ways. You can rearrange the numbers in the year 2013 sequentially, either up or down: 0,1,2,3. or 3,2,1,0.
- 0 + 1 +2 = 3
- Multiply 1,2,3 and get 6, which is the same as if you add the 1,23 and 3. (It obviously doesn't work if you multiply with a zero.
- One year. A millennium is 1,000 years. The reverse of 2013 is 3012. The difference between 2013 and 2013 is 999 years. That's one year short of a millennium.
Kids should be able to answer these questions pretty quickly --and maybe come up with some math games based on the numbers 0,1,2,3 of their own. As for champagne-sodden adults, well, now that could be interesting....
