Think of it like pulling a plough—if turning around once means facing left, then turning around *again* means you are facing right. So subtracting a negative pulls you right.
But life isn't always this neat on a line. In my paddy, if the rain is too late, no amount of hoping for a double negative will make the seedlings grow on time.
Still, when my daughter explains it from Delhi with her drawings, I see her confidence—so for her homework tonight, the rule is true.
