How Does The Japanese Soroban Abacus, Part 1: The Basics Work?

The Japanese Soroban abacus is like having a special calculator made of beads you can move with your fingers, it helps you count and do math faster!

Beads are like little blocks, and each one represents a number. The abacus has wires that hold these beads, and you slide them to add or subtract. Imagine you have 5 candies in your hand, and you give 2 to your friend, the abacus helps you figure out how many you have left by moving beads.

On the Soroban, there are two kinds of beads: upper beads and lower beads. The upper ones are like the big candies you share with friends, each one is worth 5. The lower ones are like small candies you keep for yourself, each one is worth 1.

When you want to count something, you move beads from one side of the abacus to the other, just like moving your toys from one box to another. If you move one upper bead down, it’s like saying "5", and if you add two lower beads, that makes 7!

Using the Soroban is like playing a game with numbers. Every time you solve a problem, it feels like winning a round! You don’t need to memorize anything, just move the beads, and watch the math come alive in your hands.
