Author note — to cover

Ordering and comparing values in standard form by power of ten first, then front number, with mixed lists containing ordinary numbers converted first; negative powers ordering counterintuitively. Conversion assumed from standard-form; calculation lives on the multiply-divide and add-subtract siblings. Both tiers. (N1, N9)
