Topic: art examinee score calculator
Content: the H5 page, computing function
Function:
1, the percentage of the column is optional, choose a another automatic locking
2, three box to fill in two, the third frame obtained data
3, is someone open the page, computing free for the first time, the second calculation need to send friends to use (if it is difficult to implement can also do not need to)

Resources: I have very clear with this logic, a web server
