How Long Does It Take For Trichanomis To Be Cured

Tax Clarification on Russian Multiplication

In a previous post on the letter of the NIF slipped a small error. What you need to search the table of the letters is the remainder after dividing your identity card number by 23.
The main sticking with that found many people is that calculators are not normally an operation that returns the remainder of a division, decimals calculator out directly.
Windows Calculator, as science (Click on View / Science), can get us out of trouble with the MOD key:
Write the DNI
  1. MOD press the key type 23
  2. We click on the = key (or press the Enter key on your keyboard).
Failure to hand calculator windows desktop but a stream is a bit more complicated but can also be done:
  1. divide the number of ID card of 23.
  2. The result we subtract the part that is left of the comma, ie: the number without decimals. It should be something like 0 ,....
  3. Multiply that result by 23. That number is the remainder.
Anyway I do not understand the usefulness of a letter that anyone with a pocket calculator is able to calculate in seconds. What makes a safety extra point is calculated directly from the number?

Yes, this is the Russians lately. The following is the method used by the Russian peasants to multiply numbers of any size without needing to know more than the multiplication table for two and half how to calculate a number.
Let's try to multiply 25 by 34.
wrote in a column 25 and 34 in another way: divide the number on the left by 2 (if we leave decimals, ignore them altogether), and multiply by 2 on the right:
repeat the process until the column left will be a 1: Now mark all the numbers that are left and the corresponding pairs in the column on the right:
Finally add all the numbers in the column to the right that are not crossed out:
The result of multiplying 25 by 34 is actually 850.
The method is valid for any two numbers multiply no matter how many numbers they have.

Milena Velba And Friends Is Milena Velba Married?

A Tale of Mathematics

During the early years of Stalinism, a Russian mathematician called Razin became very famous for his discoveries in number theory. Both caught the attention of the Politburo, he sent an emissary to propose a member of the party. " The party needs people like you " he argued. The poor Razin convinced him more the fear of displeasing the almighty CPSU his interest in politics, and finally agreed.
However, his interests were focused on the numbers and during boring meetings of the Party he spent playing with his theorems. That attitude did not go unnoticed for long. One evening, after leaving a friend back home gave him 50 rubles and warned him that he should not go home because the political commissars were waiting to arrest him. " Go to the station and take the first train out. Do not le digas a nadie a donde vas " le dijo.
Razín obedeció, se fué a la estación y se subió en el primer tren que vio. El tren paró en un pueblo remoto de Siberia, donde la nieve llegaba hasta la cintura. Él no llevaba ropa adecuada, ni comida, no tenia donde meterse. Intentó llegar hasta la puerta de una casa, pero como la nieve se lo impedía cogió una pala y despejó el camino hasta la puerta. En la casa no había nadie, pero como palear le hizo entrar en calor siguió haciendolo hasta que despejó toda la calle. Los vecinos, al verle tan dispuesto le acogieron en su comunidad y Razin asumió el nombre de Fiodor Alexeiev y el oficio de quitanieves.
Fiodor Alexeiev se convirtió en a man much loved in her new town. During the day removing snow from the streets at night and plunged into his world of numbers and mathematical structures.
But such popularity was not lost on local members of the Communist Party, which proposed to form part of the game. Fyodor Alexeyev
once again attempt to circumvent the offer, this time arguing that he alone was a poor illiterate workers and such a person could not be at all useful for the party. The party then was forced to attend night school where you teach literacy and the four rules. Fyodor Alexeyev resigned to his fate and went to the first night school sessions, with 24 other illiterate workers, farmers, masons, artisans ...
After a few weeks of school, the teacher wrote on the blackboard: 1 +1 = 2. He said: " This is always, in winter and summer, and always will be. Aprendanselo ." Fyodor Alexeyev
could no longer, stood up and said: You're wrong lady. I can show that under certain conditions and considering some concepts of modern mathematics this statement may not be true.
Aceca to be waxed, grabbed a piece of chalk and began to develop complicated theorems. When he had filled with formulas slate, followed other side. When he took a piece full carbon and continued to write on the walls. An hour later, at the corner of the wall ecribió its conclusion: 1 +1 = 2. Fyodor Alexeyev
the result looked puzzled and said, "Wait, this can not be wrong because I have somewhere. I will review it." At that moment they heard the sound of other classmates whispering: "Planck's constant, Planck's constant ..."

This story is not real, of course. There never was a mathematician named Razin in the USSR. But I find so beautiful that I could not resist bringing it here. Is adapted (the write directly from memory) of a book called Landscape painted with tea of Milorad Pavic .

phrases with a certain mathematical sense.

To think a little before bed:
  1. This sentence no verb.
  2. When no one reads this sentence is in English.
  3. This sentence contains an error.
  4. Here begins the sentence that you're finished reading.
  5. last words of this sentence are the words of this sentence.

Of course, the phrases are not mine, but I do not remember the authors, unless the second-appears on the book by Douglas Hofstadter Escher, Gödel, Bach. A graceful loop Eternal . A book everyone should read before you die.
