  These are not minus signs, but hyphen dashes. I don't see what exactly you're trying to achieve.

  you don't give many hints of the intention of this construct, it looks like math but you are using text mode constructs, centering is doing nothing in a raisebox as that is set in horizontal mode, you have redefined over so this will change frac and buildrel which are defined in terms of `over.

  your example uses single digits so everything aligns naturally, but does your question mean you want frac{123-1}{1-123} with the - aligned?

  Exactly @DavidCarlisle, I imagine it is a sufficient condition to keep the two minus signs aligned. As for mixing text mode with mathematical mode in addition to the likely inefficient use of centering is by lack of experience, I would be grateful for your answer to this my adding issue to the fixes and enhancements to fix what was unnecessary to use in my code so that I can learn.

  Yes, just as @marmot's answer to yours is also appropriate because you agree to increase the fraction bar thickness using hline [number] and also to decrease or increase the space between the denominator, bar, and numerator using vspace { number} or something. Now I'm looking for a way to apply a font type in a single command to the whole macro set if you have any suggestions. Thank you for your response.

  Really @marmot, for academic use it is indifferent most often the alignment of operators within a fraction. But the need to specify the position of the operators in this case refers to the fate that I intend to give inside in the education of very small children in order to facilitate the visual reading. I have used very little array command, I have tried a few different modes such as begin {align *} ... end {align *} but always with errors. I am still learning, grateful for your help and all who have made further comments.
