Usage and domains

In mathematics and related disciplines, kompleksiset luvut translates to complex numbers, a standard term in Finnish for numbers of the form a + bi. The expression appears in textbooks and lectures as a routine descriptor of objects or problems that require reasoning about both real and imaginary parts. Beyond mathematics, kompleksiset is used to describe things that have multiple interconnected parts or layers, such as kompleksiset tilanteet (complex situations), kompleksiset rakenteet (complex structures), or kompleksiset ongelmat (complex problems). In everyday language, the term often carries a sense of intricacy or difficulty, though in casual speech monimutkainen is a more common synonym for not simple.
