Mathematical proof is important for mathematical student at college, but many mathematical student at Indonesian college can't learn mathematical proof well. They feel that mathematical proof is so difficult. The research is focused on looking for the answer of the question “ why Indonesian mathematical college student can't learn mathematical proof well?” and “what is the solution?”. The effort to answer the question have be reported on Indra Siregar's article in 2015
with the title “Mathematical proof learning for beginner”, but the researcher found some new information based on the data in that article. The reseacher found that Indonesian mathematical college student can't learn mathematical proof well not only caused by bad logical mathematic ability and the lack of sources books for beginner, but the lack of experience on handling nonroutine mathematical problem. We have two kinds of solution to solve the problems, that is shortterm solution and long-term solution
