Plus is the two lines together, minus is the distance/difference in my head at least

    If plus was ⤚ (U+291A RIGHTWARDS ARROW-TAIL) meaning 2 lines coming together and then being 1 line that's twice as long [or twice as thick], that would be intuitive to me for adding.

    I can't think of an intuitive sign for minus, maybe something with empty space in it?
