**Is there any benefit to learn mathematics?** Learn mathematics does have benefits for children. Mathematics can train brain, help them build logic thinking,
continue learn mathematics can help children build confidence, living skills and goals.

**This mathematics learning website is designed for all students, parents, and teachers.** Learning mathematics by understanding principles from examples
is a good way. How to solve a mathematics problem? There is a way and process for it. First we need to identify which category the particular problem is
belong to, second we need to know what principle are related to solve this kind of problem, third we need to use the technique we learn from mathematics
classroom to solve the problem. For example, if we are asked to measure the height of a tall building, we need to identify which category the problem belong to.
Since the height of the building is perpendicular to the ground, we can draw a triangle in which the height of the building is the altitude of
the triangle and another leg of the right triangle is the ground. Since the building is too tall to measure it directly, so we use two similar
triangles to find the height of the tall building. The altitude of the small triangle can be measured. The altitude of the small triangle is the line drawn
from a point which lies on the hypotenuse of the large triangle and perpendicular to the ground. Then we apply the properties of similar triangles, we can find
the height of the tall building.
