Hi, all. I know the answer to this one, but would just like an explanation of the maths.

My understanding is that -(-(-(-2))) == -2 is false because -(-(-(-2)) equates to positive 2, which therefore means 2 == -2 is false.

I read it as a negative multiplied by a negative equals a positive, therefore -2 * -2 = 2. But what do the parenthesis and the minus signs all clustered together mean? I've never learned this in math. Is it negative zero multiplied by something, or negative one, etc? I really have no idea!

Thanks
