+<h3>Hebrew Numerals</h3>
+<p>Hebrew numerals are an alphanumeric system where letters of the Hebrew alphabet are assigned numerical values. Known as "gematria," this system has been used for centuries in Jewish tradition.</p>
+<h3>How it works</h3>
+<p>Letters represent values from 1–9 (units), 10–90 (tens), and 100–400 (hundreds). Numbers are written by combining letters, with the larger values first. A single apostrophe (geresh, ׳) follows single-letter numbers, and a double apostrophe (gershayim, ״) is placed before the last letter of multi-letter numbers.</p>
+<h3>Special cases</h3>
+<p>15 and 16 use טו and טז instead of יה and יו to avoid writing God's name.</p>
+<h3>Units (1–9)</h3>
+<div class="theory-example">א  ב  ג  ד  ה  ו  ז  ח  ט</div>
+<p>(א=1, ב=2, ג=3, ד=4, ה=5, ו=6, ז=7, ח=8, ט=9)</p>
+<h3>Tens (10–90)</h3>
+<div class="theory-example">י  כ  ל  מ  נ  ס  ע  פ  צ</div>
+<p>(י=10, כ=20, ל=30, מ=40, נ=50, ס=60, ע=70, פ=80, צ=90)</p>
+<h3>Hundreds (100–400)</h3>
+<div class="theory-example">ק  ר  ש  ת</div>
+<p>(ק=100, ר=200, ש=300, ת=400)</p>
+<h3>Beyond 400</h3>
+<p>Numbers above 400 are written additively by combining tav (400) with hundreds:</p>
+<div class="theory-example">500 = ת״ק = 400 + 100<br>900 = תת״ק = 400 + 400 + 100</div>
+<p>Thousands are written as the units letter followed by geresh:</p>
+<div class="theory-example">1000 = א׳<br>5000 = ה׳</div>
+<h3>Example</h3>
+<div class="theory-example">5786 = ה׳תשפ״ו = 5000 + 400 + 300 + 80 + 6</div>
