Seems like a bad transcription of an interview with the researcher.
In the actual journal article they either used an underline or nothing at all, eg. "6 + 9= __ + 4" and "__ + 3 = 5 + 7 = "
I'm also not really surprised since as other posters have mentioned I don't really remember learning any real algebra until 6-8 grade.
This really just means that Chinese kids learn this stuff earlier than US kids and maybe US kids should learn it early on as well.
