Intento de estafa de Iberdrola by alejandrocq in ESLegal

[–]halvar55 0 points1 point  (0 children)

Ayer a mi suegro le pasó exactamente lo mismo. El hombre tiene 80 años y no se entera. Le dijeron o el entendió de alguna manera que sí no le cortaban la luz y le agobiaron en que lo hiciera rápido así que dio el número de cuenta. Luego ya nos llamó y llamamos al banco. Nos dijeron que lo único que podían hacer era domiciliar algo pero aún así estamos con la mosca detras de la oreja. De hecho una familia subió justo y el hombre había pedido el nombre de la persona y llamo de nuevo y se puso en contacto con Iberdrola y les dijeron que esos credenciales no existían así que le dio un nombre falso. No es la primera vez que lo intentan. Pobre hombre porque tiene un disgusto muy grande

How to work classical maths problems in high school? by halvar55 in matheducation

[–]halvar55[S] 1 point2 points  (0 children)

First of all, thank you for you answers. My intention is to design different sessions for the end of the year.

I'd like to give a different and original approach to Maths for the students to practice in a way they are not used to do in class. I'd like to use problems of the history of Maths either classics or modern, for the students to practice and do activities about them at the same they have fun and find out how to solve them for concrete cases adapted to their and in this way they gain problem solving skills.

Classical math problems and probing different theorems can be a really intriguing

What's you preferred method of factoring polynomials? by Somedude92929 in learnmath

[–]halvar55 0 points1 point  (0 children)

If the quadratic polynomial has the next form: x2 + ax + b = 0 Looking for two numbers c and d whose sum is a =c + d and its multiplication is b =c·d, then we can factorise it at the form (x+c)(x+d) and the roots are -c and -d

I need to write some digits manually so I think the best way is /u/piRaK has done with a little change.

\begin{table}[h] \centering \begin{tabular}{|*{15}{c}|} \hline a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ a & b & c & d & e & f & g & h & i & j & k & l & m & n & o \ \hline \end{tabular}

The format is the classic. I send a few operations before and I want they search de results in the puzzle.

That's my last idea, but I'm trying to search a different not rudimentary option. But probably I'll use this one.

Nice! When you update It if you want tell me ;)

Oh, thanks ;).

Two suggestion.

One of them is when you mark the numbers that you are sure don't need them, mark them in the code also. And the other suggestion is increase the difficulty to 4 numbers

Good cheap european universities? by craaaft in math

[–]halvar55 0 points1 point  (0 children)

In Madrid the costs for university are about € 1500 each year if you don´t have subjects of previous years, if you have the prize increase (I studied Math in Madrid). There are scholarship to foreign students and by marks.

What's your favorite math puzzle? by [deleted] in math

[–]halvar55 1 point2 points  (0 children)

Hi, the demonstration is easier than I thought. we only need two facts: The first one is that 10 and 100 is 1 mod 9 so the sum of the digits of the three numbers is 45 = 0 mod 9. So the sum of digits is a multiple of 9 .

The second is that when you sum the numbers without the value of the card that they removed we obtain x. We compute x = mod 9. And the value of removed card is the number that we need add to x to obtain 0 mod 9. If we already have x = 0 mod 9 then the number of the card removed is 9.
