+<h3>Greek Numerals</h3>
+<p>Greek numerals are a decimal system that uses letters of the Greek alphabet to represent numbers. Known as Ionian or alphabetic numerals, this system was adopted around the 4th century BC.</p>
+<h3>How it works</h3>
+<p>Letters are assigned values from 1 to 9 (units), 10 to 90 (tens), and 100 to 900 (hundreds). A special mark (´, keraia) is placed after the number. Thousands are indicated by a subscript mark (͵) before the units letter.</p>
+<h3>Units (1–9)</h3>
+<div class="theory-example">α  β  γ  δ  ε  ϛ  ζ  η  θ</div>
+<p>(α=1, β=2, γ=3, δ=4, ε=5, ϛ=6, ζ=7, η=8, θ=9)</p>
+<h3>Tens (10–90)</h3>
+<div class="theory-example">ι  κ  λ  μ  ν  ξ  ο  π  ϟ</div>
+<p>(ι=10, κ=20, λ=30, μ=40, ν=50, ξ=60, ο=70, π=80, ϟ=90)</p>
+<h3>Hundreds (100–900)</h3>
+<div class="theory-example">ρ  σ  τ  υ  φ  χ  ψ  ω  ϡ</div>
+<p>(ρ=100, σ=200, τ=300, υ=400, φ=500, χ=600, ψ=700, ω=800, ϡ=900)</p>
+<h3>Example</h3>
+<div class="theory-example">ηπε = 8 + 80 + 5 = 93’</div>
