Hand-brain fast calculation is an efficient, fast and simple calculation method. By using hands and brains, it turns complex calculation into simple operation and counting, and trains operators to think positively, reversely, logically and abstractly.

Use both hands and brain.

Hand-brain quick calculation is an efficient, fast and simple calculation method, which uses both hands to calculate, and both hands and brain divide their work and coordinate their work. From hand calculation to brain calculation, it is to see if the brain can calculate, and calculate with both hands.

Fast computing technology of hand-brain analog computer

Hand-brain fast calculation is called hand-brain analog computer fast calculation technology. Its principle is to convert complex calculation into simple operation and counting according to the zero-sum theory of computer.

Promote cerebral blood circulation

Hand-brain velocity algorithm promotes brain blood circulation and stimulates brain cell activity through the high frequency activity of the operator's hand.

Train positive thinking and reverse thinking.

The learning process of hand-brain quick calculation trains the operator's positive thinking, reverse thinking, logical thinking and abstract thinking.
