negative numbers are unreal
I believe that the number line goes no lower than "0". Negative numbers are unreal, and formed from non-circuitous mathematics. No one can show me -1 atom. A debt is not made of less than a vacuum, it is a mandelbroting of various other #s and number portions that together produce "at least zero". There is no real 'less than zero'.
This eliminates all debts into their kind and form.
Something under 0 is not a negative number, it is portions of other things to be turned to 0. These other things can be examined and valuated above 0.
