Their meaning is approximately the same as that of square brackets in mathematics: buy albania telemarketing data with them, the subsequent operation will be carried out not with the last element, but with the entire group.
Example of decryption
Usually in scientific journals we deal with not very long UDC indexes. But for clarity, let's try to decipher a more complex example - a composite one with determinants.
781.7(519.5)(02.068)=131.1
Let's break this code down into its elements:
781.7 – Theory and forms of national music of individual peoples and countries;
(519.5) – South Korea (5 – Asia, 51 – Central and East Asian countries, 519 – Korea);
(02.068) – Rare books (02 – Books in general);
=131.1 – Italian language (1 – Indo-European languages, 13 – Romance languages, 131 – Italo-Romance languages).
We receive "A Rare Book on the Theory of Forms of National Music of South Korea in Italian".
