画面随机产生两个不同颜色运算数字图案， 1.“掉下来数字图案”为“蓝色水滴图案”。 2.“下面随机左右位置出现的数字图案”为“黄红色火圈图案”。 随机出现“大于”“小于”“等于”三种运算，当蓝色水滴图案碰到黄红色火圈图案时，会检查运算结果是否正确。若正确则得1分，若不正确则扣1分。 The screen randomly generates two different color arithmetic figures, 1. "drop down digital pattern" is "blue water droplet pattern". 2. "the digital pattern in the random position below" is "the yellow red ring pattern". The three operations of "greater than", "less than" and "equal" appear randomly. When the blue water droplet pattern touches yellow and red pattern, it will check whether the operation result is correct. If it is right, it will get 1 points, and if it is not right, it will deduct 1 points.
