I made a Google search, but couldn't find any answer. I'd like to know the names of the operators

+, -, x, /, =, <, >, %, {, }, (, ), :, &, etc.

Also I would appreciate links pointing to such symbols if there are any.

Here is a page on wikipedia dedicated to mathematical symbols:

Also there is a category:

For example on the main page you can find a sidebar with links to pretty much all of the symbols from your question.

UPDATE: Symbols mentioned in original question:

+ - плюс, знак сложения. Related operation: сложение (addition).
- - минус,знак вычитания. Related operation: вычитание (subtraction).
x,* - знак умножения. Related operation: умножение (multiplication).
    More specific:
      x - крестик (applicable to symbol only not to the mathematical operation itself)
      * - звёздочка (symbol only);
/,: - знак деления. Related operation: деление(division).
    More specific:
      / - косая черта (symbol only);
      ÷ - обелюс (symbol only);
      : - двоеточие (symbol only);

= - знак равенства. Related operations: равенство(equality), присвоение(assignment).
- знак тождественности. Related operation: сравнение по модулю(congruence relation, as in modular arithmetic)
< - меньше (literally less)
> - больше (literally greater)
% - знак процента, процент
() - скобки, круглые скоки
( - открывающая скобка
) - закрывающая скобка
{} - фигурные скобки
<> - угловые скобки
[] - квадратные скобки
& - амперсанд (symbol only). Operation: логическое И,И (logic AND),побитовое И(bitwise AND)
. - точка (symbol only, literally point). Also, десятичная точка (decimal point), десятичный разделитель (decimal separator)

  • Thanks for taking the time,I actually hoped to find it in en.wikipedia.org/wiki/Russian_alphabet . but seems it is not there.

    I edited the translation of сравнение since its technical meaning in math would be called "congruence" (as in 8 = 2 mod 3), even though its everyday meaning translates as "comparison".

  • @Kcd, thanks for your edit. But in most of the cases I faced modular arithmetic russian texts tended to use ≡ (знак тождественности) for this (like b ≡ r mod n). I understand your point, though. Comparison really sounds wrong. Maybe I should just replace it with равенство (equality) Commented Jun 15, 2012 at 13:52

    @defaultlocale: I agree ≡ should be used instead of = in modular arithmetic, but I don't know how to produce ≡ directly from my keyboard. In retrospect I could have just cut and pasted it from some webpage, just as I have done now with the ≡ that you put in your comment.

    I never heard word обелюс in Russian for ÷ except as an answer to the question like ‘How this character per se may be called?’ Since it’s used in electrical engineering as range sing, e. g. 10÷15 mA, and never for division it may be called simply знак диапазона or тире (dash) if you do not want to pay attention to the dots above and below.
