system for counting in a game</figcaption></figure> <p>A <b>numeral system</b> (also called a <b>number system</b> or <b>system of numeration</b>) is a way to write <a href="/wiki/Number" title="Number">numbers</a>. <a href="/wiki/Roman_numerals" title="Roman numerals">Roman numerals</a> and tally marks are examples. "11" usually means eleven, but if the numeral system is <a href="/wiki/Binary" title="Binary">binary</a>, then "11" means three. </p><p>A numeral is a way to represent a number. It may be a <a href="/wiki/Symbol" title="Symbol">symbol</a> or a <a href="/wiki/Word" title="Word">word</a> in a <a href="/wiki/Natural_language" title="Natural language">natural language</a>, or a group of them. Numerals differ from numbers just as the word "rock" differs from a real rock. The symbols "11", "eleven" and "XI" are all numerals that represent the same number. <a href="/wiki/Babylonian_numerals" title="Babylonian numerals">Babylonian numerals</a>, <a href="/wiki/Greek_numerals" title="Greek numerals">Greek numerals</a> and Roman numerals are among the systems that were long used, before the <a href="/wiki/Hindu%E2%80%93Arabic_numeral_system" title="Hindu–Arabic numeral system">Hindu–Arabic numeral system</a> largely replaced them. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Bases">Bases</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Numeral_system&veaction=edit&section=1" title="Change section: Bases" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Numeral_system&action=edit&section=1" title="Edit section's source code: Bases"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Various symbols are used as numerals to make numbers. A system with base 10 (the common <a href="/wiki/Decimal" title="Decimal">decimal</a> system), normally uses the symbols <i>0</i>, <i>1</i>, <i>2</i>, <i>3</i>, <i>4</i>, <i>5</i>, <i>6</i>, <i>7</i>, <i>8</i>, and <i>9</i>. Each of the numbers 0 to 9 can be written as one symbol, <i>0</i> ... <i>9</i>. To count past 9, symbols have to be put together. <i>10</i> can be seen as <i>1</i> in the tens' place and <i>0</i> in the ones' place, or as <i>1 times 10<sup>1</sup> plus 0 times 10<sup>0</sup></i>. With a base of 2, only the symbols <i>0</i> and <i>1</i> are used. <i>10</i><sub>base 2</sub> is therefore <i>1 times 2<sup>1</sup> plus 0 times 2<sup>0</sup></i>. This is the same as 2, in the base 10 notation. </p><p>For bases bigger than 10, capital letters are used as symbols. For example, the <a href="/wiki/Hexadecimal_numeral_system" class="mw-redirect" title="Hexadecimal numeral system">hexadecimal numeral system</a> (base 16) uses the <a href="/wiki/Numerical_digit" title="Numerical digit">numerical digits</a> 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. </p><p>Today, base 10 is the most commonly used system.
