I Use Hearthstone to Solve Science Questions

I have given five methods: the straight-line distance geometric method, the parabolic geometric method, the vector method, the cubic Vedic theorem method of one variable, and the median substitution method. If you come up with the next one, you will win. But now you only give three methods: the quadratic Vedic theorem method, the variance inequality method, and the arithmetic substitution method. You only have seventeen cards left. If you can come up with three more solutions from your seventeen cards and defeat me, I will eat all the cards on the spot. Sorry - I won the two matching methods and the solid geometry method. Gongquan High School was the most famous high school in the country. All students in it competed to improve their rankings. The competition was mainly based on problem-solving battles that incorporated the rules of board and card games such as "Hearthstone", "Gwent", and "Magic: The Gathering". Our story begins with a person who is obviously a bad student but has to pretend to be a top student.
