Feelings of perceptive ability of the strong sense of number will be better, for some numbers will be more or more sensitive. On the contrary, it is more sluggish, or even do not know what the meaning of numbers means, even if repeatedly taught to explain, it is difficult to get started. It can be said that the degree of number of strong and weak, for learning mathematics is crucial. Strong sense of number of people, learning mathematics are generally faster, the ability to understand mathematical knowledge is relatively strong, math results generally better. The number of weak students, mastery of mathematical knowledge in general will be relatively poor. This view is not absolute, it is difficult to use a number to describe or explain.
