It seems like @bubbleBlower might be interested in something in the range from -15 to 0, or perhaps an imaginary number like "i" or "-i" or even a complex number like "3i+12" or some such. Other options are available for numbers represented by a single symbol, π and "e" are classic. If you're willing to stray somewhat outside of the range of numbers into number-adjacent concepts, might I even suggest ∞?
are you sure these are numbers? theres a lot of letters in there i think. wait, unless those were numbers all along and ive been using them wrong??? ohhhhh fuuuuck
