In this video, we delve into the fascinating process of crafting an abacus, a traditional calculation tool that has stood the test of time. Watch as we guide you through each step, showcasing how sliding counters along rods and grooves enable precise mathematical functions. Discover not only its basic operations—addition, subtraction, multiplication, and division—but also its capability to calculate cubic roots. Join us on this journey to uncover the art and science behind this ancient instrumen

Faster Than Calculators? The abacus hand method is a mental math technique where practitioners use finger movements to simulate an abacus in their minds. Though it might look like random gestures, each motion represents a specific value, allowing for lightning-fast mental calculations. This method originates from traditional abacus training, especially in countries like Japan, China, and India, where students learn to visualize bead movements without needing a physical tool. Studies have shown t
