Methodology When we learn a new subject, the first step is to learn words or concepts in this subject. It is like that you need to expand your vocabulary in the field first, then to understand and use these terms / jargons to analyze and solve questions in this field. This, naming a thing, is […]Read More "Maths – Data Descriptions"
