If your positing history is true, you are taking Probability and Vector Analysis only now. It seems, you have a long way to go till you get to the courses that are considered respectable (sorry) for a Math PhD applicant (sorry). Are you going to apply next year? My advice would be to lighten up on History courses, and get really involved in Math, if you want PhD in Math.
Yes, sure, go for the Math Subject GRE, and try to get into the 80% - this will beat your sub 3.0 GPA. TRy it several times. You can have three attempts before the next years’ application season. And aim for the schools below first 100 or 150. If possible at all - get into some projects to show you can do research. Is it possible for you to do some grading or TA-ing? Graduate Math programs need “warm bodies” to be teaching assistants and graders, so they do need to admit people.
Thus, I’d work on improving the resume, towards showing research potential, teaching potential, and Math GRE. And make sure you have 170 on the math portion of the general GRE.
