+<p>
+V <a href="http://en.wikipedia.org/wiki/Reverse_Polish_notation">inverzni poljski ali postfiksni notaciji</a> ne potrebujemo oklepajev:
+računska operacija sledi številoma in se vedno izvede takoj ter zamenja predhodni števili in operacijo z rezultatom operacije.
+
+Poglejmo si računanje <code>(3 + 5) * 2 - 10 * (2 - 1)</code> ali postfiksno <code>3 5 + 2 * 10 2 1 - * -</code>:
+
+<ul>
+<li> Beremo vhod do prve operacije. </li>
+<li> <code>3 5 + </code>; izvede se seštevanje, tri elemente zamenja rezultat 8, beremo dalje. </li>
+<li> <code>8 2 * </code>; rezultat je 16, beremo dalje.</li>
+<li> <code>16 10 2 1 -</code>; rezultat 1, beremo dalje.</li>
+<li> <code>16 10 1 *</code>; rezultat 10, beremo dalje.</li>
+<li> <code>16 10 -</code>; rezultat 6, beremo dalje.</li>
+<li> <code>6</code>; vhoda je konec zato se se računanje ustavi.</li>
+</ul>
+Napišite kalkulator s celoštevilskimi operacijami seštevanja, odštevanja, množenja, deljenja in izračunom ostanka,
+ki prejme vhod v inverzni poljski notaciji. Ko uporabnik ne poda ničesar (pritisne le enter), naj se program zaključi.
+Števila ter operande ločujte s presledkom.
