I Pill) to understand. The truth is that it is a real crap, so (the community) do not expect any rigor ^ ^ U
all started with a nonsense: In Thursday's edition of
infumable and free daily tabloid "Què
!
. " In one of its pages, propose one of those curious mathematical games that seem to figure out what we think.
The game is proposing that, from a fact as trivial as many times as we wanted to eat chocolate a week, will be able to guess our age
. First you'll here the jueguecillo, for fun (and hallucinate pickles, why deny it ¬ ¬ U) for a while:
How many times a week you feel like eating chocolate? It must be a number greater than 0 and smaller than 10, think again. Multiply this number by 2 (to be even). Throw in
5. -
Multiply the result by 50 (id turning the calculator ...) -
If you have already completed years in 2006, added to the number that you got 1756. If you have not already done so, Throw in 1755. -
Subtract the year you were born. -
-
-
RESULT: You get a three-digit number, right? The first number is how many times you feel like eating chocolate. And the second ... It's your age! - [E]: That is the way to say that this figure depends on the independent variable x: the number of times we feel like having chocolate (x), and has a different parameter for each person, year of birth (n).
The final number, then, as we have seen, what we get after making a series of operations which set the guidelines we give them step by step, and so explicitly. From the figure
x , we do what we ask, and express it mathematically. Overall, we're going to write a function, a formula, we collect all the operations we have been doing:
a)
"Multiply that number by two":
f (x) = 2 · x
& nbsor "
f (x) = (2x + 5) • 50 + 1755
or
f (x) = (2x + 5) • 50 +
1756 [to follow the example of 1756]
e) "Subtract your date of birth"
f (x) = (2x + 5) • 50 + 1756 - No
And this is the final formula we get. But it is not "fachion" ¬ ¬ U Come to fix it, to discover his dirty trick. If we operate on the brackets and do the multiplication:
CHTMLa:
- The
blue part is, surprisingly, the current year remains our date of birth. The calculator, cash is not a telepath, and here we have "given" this information about our age. It is well known that for
calculate the age of a person
you only have to subtract the current year's date of birth, and obtain a two-digit number (tens and units) : DU (such as in 14 (10 tens + 4 units)).
- The green part
simply multiplied by 100 the current number , giving the position of the hundreds ALWAYS (ie Telecupón and U): If we have chosen 3 times a week2 and for year of birth, 1904:
f (12) = 12,100 + (2006 - 1904) = 1200 + 102 = 1302
Come on, that neither the grandmother wanted to eat 13 times or have 2 years xD The method is no longer feasible to older than 99 years, for example. Total that this has been my dissertation of the month ¬ ¬ U I know, is messy at times, I'll explain with the ass and is boring paragraph ("viva la numerasión" ¬ ¬ U), but if you look there nothing unusual, only addition, subtraction and multiplication. And supuestísimo: The number you choose in the end it has NOTHING to do with chocolate xD It could be done as often as you like going to the movies, the children you have, etc, and that chocolate is simplement the fancy way of saying "choose a truly random number between populations within the range")
I hope to update more in a few days, and if a line item from my "informative" (where is the key 40 quotes together?), which is at least a subject more interesting than this stuff xDDD Yes, next take cute figurines that this did not invite it, sorry ^ ^ U For questions, complaints and letter bombs, Comments;)
