Triangular Numbers, Tetrahedral Numbers, and the NERDY Numbers that Produce Them

5/30/2015

Triangular Numbers: The decimal expansion of the inverse of 999,700,029,999 produces a sequence showing the triangular numbers. 1/99970002999 = 0. 0000 0000 0001 0003 0006 0010 0015 0021 0028 0036 0045 0055 0066 0078 0091 0105 0120 0136 0153 0171 0190 0210 0231 0253 0276 0300 0325 0351 0378 0406 0435 0465 0496 0528 0561 0595 0630 0666 0703 0741 0780 0820 0861 0903 0946 0990 1035 1081 1128 1176 1225 1275 1326 1378 1431 1485 1540 1596 1653 1711 1770 1830 1891 1953 2016 2080 2145 2211 2278 2346 2415 2485 2556 2628 2701 …

Tetrahedral Numbers The decimal expansion of the inverse of 9,996,000,599,960,001 produces a sequence showing the tetrahedral numbers. 1/9996000599960001 = 0. 0000 0000 0001 0004 0010 0020 0035 0056 0084 0120 0165 0220 0286 0364 0455 0560 0680 0816 0969 1140 1330 1540 1771 2024 2300 2600 2925 3276 3654 4060 4495 4960 5456 5984 6545 7140 7770 8436 9139 …

Brain'o Quiz # 9

5/29/2015

Mr. B’s “BRAIN-O” Quiz

Guaranteed to unclog clogged up brains!

NAME:__________________ DATE:____________ PERIOD:_______

Directions: Carefully read and answer the following questions.  Print you answer clearly in the box next to each question.  Questions are worth one zillion nano bonus points each.  However, if you get all five correct, we will double the points for a total of ten zillion nano bonus points.

1.		In New York, a woman married ten different men from that city.  None of the men died, and she never divorced, yet she never broke any laws.  How was this possible?
2.		A taxi driver was called to take a group of passengers to the airport.  The airport is normally an hour away, but with traffic being extra slow, it took a full hour and half an hour.  On the return trip the traffic was still heavy, but it only took him 90 minutes.  Why?
3.		Which is grammatically correct?  Should you say “The yolk of an egg is white.” or “The yolks of eggs are white.”?
4.		An electrician and a plumber attended the “International Home Show.”  One of them was the father of the other’s son.  How could this be possible?
5.		Using any combination of parentheses and the operation symbols (+, -, x, and ÷), how can you arrange the numbers 6, 6, 6, 6, and 6 into a mathematical expression equal to 8?

The problem is not that there are problems.

The problem is expecting otherwise

and thinking that having problems is a problem.

Cyclops, Binocular, and Trinocular Primes

OEIS has a listing for Cyclops Primes - prime numbers that have one zero right in the middle, but nowhere else in the prime.  The one zero represents a Cyclops' one eye.  And they also note that the prime must have an odd number of digits, otherwise the one zero can't be "right in the middle"

But I noticed that they left out a listing for those of us with two eyes.  So I have been searching for Binocular Primes, to represent those of us with two eyes.

Binocular Primes (or maybe I should name it Biclops Primes): Prime numbers that have two zeros (representing two eyes) in the center of the prime. 1,009   2,003   3,001   4,001   4,003   4,007

Then I started to think (I do that from time to time) “What if giant with two eyes married a giant with one eye (a cyclops)?”  If they had offspring would the gene for one eye be the dominant gene, or the gene for two eyes?  Or could the offspring end up with both and end up with a total of three eyes?  So I started looking for Triclops Primes.

Triclops Primes: Prime numbers that have three zeros in the center of the prime number.  The three zeros represent three eyes. 10,007   10,009   40,009   70,001   70,003   70,009   90,001   90,007
