Who coined terms such as degrees in mathematical equations?
The terms "yuan" and "times" in mathematical equations were created by Emperor Kangxi of the Qing Dynasty. When missionaries explained mathematical equations to Kangxi, they often couldn't explain them clearly because of their limited translation level. Emperor Kangxi suggested that the unknown be translated into yuan, and the highest number into times, so that the values of the unknown equal to the left and right sides of the equation can be translated into roots or solutions.
