腦珠算全教程(初階) for PC

"Brain Abacus Full Course (Beginner)" covers basic to advanced mixed addition and subtraction, as well as quick arithmetic. The course is mainly divided into two parts, namely the interactive tutorial and the two-handed beading demonstration.

Rich interactive graphic explanation:
The interface design is simple and easy to understand. Rather than relying solely on text to explain, each concept is provided with detailed diagrams and diagrams for comparison and explanation, eliminating language misunderstandings and obstacles, explaining difficult theories more effectively, simplifying complexity The process, in-depth explanation of each complex key point. At the same time, each class is covered with a large number of examples, and each example has a step-by-step detailed demonstration, making self-study easy.

Two-handed beading demonstration:
The bead dialing demonstration device allows us to input a number or an arithmetic formula, and the system will automatically demonstrate the bead dialing and calculation step by step on the abacus and explain in detail. We can even pause the current step at any time and carefully observe the description, or replace it with another Questions or numbers for a new round of demonstrations.

Analog abacus:
With the analog abacus, we can start computing at any time. The built-in analog abacus in the classroom allows everyone to follow the class at any time, and practice the method of moving beads with both hands on the abacus at the same time. You can either follow the illustrated steps on the page to synchronize the operations, or you can try the operations first, and then check with the corresponding demonstration steps.

Content style:
- Introduce the theory of abacus mental arithmetic and basic abacus addition and subtraction
- A detailed introduction to the method of hand-carrying beads
- Addition and subtraction of units up to multiple digits
- Introduces quick arithmetic for speed and fun
- Built-in simulation abacus for synchronizing practice at any time
- Demonstration problem solver showing detailed steps for numbers or calculations
- With many illustrated examples as a learning guide
