Should I report a 650 mGRE for Masters programs?

[coup]

I'm interested in applying to top MS math/stats programs. I did not study math in undergrad (studied business with just two first year math courses), but have had a couple years of work experience in stats and data science. I took the math subject GRE in hopes of demonstrating some mathematical ability since I do not have math courses on my transcript that can do that, but only got a 650 (49%). FWIW, I had a couple of months to study math in order to prep for the test while holding a full time job.

My question is, would including this score strengthen or weaken my application? The mGRE is completely optional, and I got 170 on the math section of the general GRE, but of course my transcript is weak on math. 

What do you guys think?
