I just got my sat subject scores back, but should I send them?

Hey guys,
I recently got my sat subject scores back. And I’m not sure if I should send them or not, because their low. I’m applying to uci, ucsc, ucd and ucr.
My scores are:
Math 1- 590
Bio e- 510
Literature- 550

don’t send. scores all very low
general rule of thumb is send 700+
