正向速算 脑力世界杯
计算是大脑数理逻辑推理能力的综合应用，是理解力水平最直观的体现。正向速算是综合训练大脑注意力、理解力和记忆力的重要项目。本项目侧重于面向普通人通过简单的加减乘除运算考查大脑计算的速度和准确性，重在脑力素质的训练。
Computation is the comprehensive application of mathematical logic reasoning ability of the brain, and it is the most direct embodiment of comprehension level. Fast calculation is an important project to train brain's attention, comprehension and memory. This project is focus on ordinary people through simple addition, subtraction, multiplication and division to check the speed and accuracy of brain computing, focusing on the training of mental quality.
