The MSC is a hierarchical scheme, with three levels of structure. A classification can be two, three or five digits long, depending on how many levels of the classification scheme are used. The first level representing the main mathematical disciplines is labeled by a two digit number, the second representing specific areas is labeled by a letter (or a hyphen), and the third level for specific kind of mathematical object or a well-known problem or research area is labeled by another two digit number.</p> </section> <section class="unit-subject-list unit"> <ol> <li>00-XX <a href=" /subject/MSC/00-XX"> General </a> </li> <li>01-XX <a href=" /subject/MSC/01-XX"> History and biography </a> </li> <li>03-XX <a href=" /subject/MSC/03-XX"> Mathematical logic and foundations </a> </li> <li>05-XX <a href=" /subject/MSC/05-XX"> Combinatorics </a> </li> <li>06-XX <a href=" /subject/MSC/06-XX"> Order, lattices, ordered algebraic structures </a> </li> <li>08-XX <a href=" /subject/MSC/08-XX"> General algebraic systems </a> </li> <li>11-XX <a href=" /subject/MSC/11-XX"> Number theory </a> </li> <li>12-XX <a href=" /subject/MSC/12-XX"> Field theory and polynomials </a> </li> <li>13-XX <a href=" /subject/MSC/13-XX"> Commutative algebra </a> </li> <li>14-XX <a href=" /subject/MSC/14-XX"> Algebraic geometry </a> </li> <li>15-XX <a href=" /subject/MSC/15-XX"> Linear and multilinear algebra;
