The Abacus is one of the oldest mathematical tools used for performing calculations. It helps develop mental arithmetic skills and is widely used to improve concentration, memory, and problem-solving abilities, especially in children.
An Abacus is a manual counting device consisting of rows of beads that slide along rods. Each bead represents a number, and by moving them in a specific way, one can perform addition, subtraction, multiplication, division, and even square roots.
📌 History of Abacus
📌 Types of Abacus
1️⃣ Chinese Abacus (Suanpan) – Has two beads on top and five on the bottom
2️⃣ Japanese Abacus (Soroban) – Has one bead on top and four on the bottom (most commonly used)
3️⃣ Russian Abacus (Schoty) – Uses horizontal rods with 10 beads each
4️⃣ Modern Digital Abacus – Used in apps and online learning
📌 How the Abacus Works
The Abacus is divided into two parts:
🔹 Upper Deck – Carries higher place values
🔹 Lower Deck – Carries units and lower values
Each column represents a place value (Ones, Tens, Hundreds, Thousands, etc.).
✅ Addition & Subtraction – Moving beads up/down to increase/decrease numbers
✅ Multiplication & Division – Using repetitive addition/subtraction techniques
✅ Square & Cube Roots – Advanced abacus techniques
