I don't speak your language, but I hope you do understand English. In this article about complex numbers there is a common widepread error. In the definition of a complex number as an expession a+bi, the imaginary unit i should not be defined as , because it is in this stage unknown what this should mean, and there is the ambiguity of which root to choose, but i should be introduced as imaginary unit with the property i2 = − 1, which property is used in calculating.130.89.222.126 20:38, 11 Rugpjūčio 2006 (EEST)

  It is said that i = is imaginary, it is not mistake. --Atlantas 20:48, 11 Rugpjūčio 2006 (EEST)
    I don't know who said this, but it is not true. After defining complex numbers, without using a square root, it is possible to define a kind of square root for complex numbers. Either it is multiple valued, or a special main value is to be chosen. 130.89.222.126 14:55, 12 Rugpjūčio 2006 (EEST)
