Reply to comment by mercifulcrocodile in TIL that +/- 42k years ago, the “Adam’s Event”, a reversal of Earth’s magnetic poles, may have led to the extinction of mega fauna, Neanderthals, and forced humans into caves as the earth experienced intense periods of cosmic radiation, solar winds, electrical storms, and drastic climate change. by GonzoVeritas

That's the typical usage of +/-. I've never seen it used as "approximately". Instead, I'd use "~", eg "~45k years ago".

+/- as used in the title was pretty confusing to me
