Absolute Nullity-Positivity True Boundary Cardinal or AN-PTBC is an unimaginably small number, it's defined as the real boundary between nullity (0) and positivity (>NBCU), so if NBCU says getting smaller than it is nonsense and will pop out of existence, for this number that is a joke, because this number is the boundary between 0 and positivity, if any number ignores this and gets smaller it will be just 0, as this is a real boundary, it is theoretical that this number is "positive", so that means this number is nothing and something at the exact same time.
Going smaller than this will result in 0, the boundary is ridiculously smaller than NBCU, this number is the border to nullity (0).
If we take for example TNL x AN-PTBC, the result will be equal to AN-PTBC, and AN-PTBC x TLNotW (TLNotW for "The Largest Number on the Wiki"), the result will be equal to 1 or NBCU, the word "nonsense" is fake for this number, as it is a boundary (already said too much times).
