Chinese remainder theorem

The LaTeX command "cases" introduces a left curly bracket; it is intended to be used, for example, when providing a definition of a function by cases, where there is a left side of an equation prior to the list of expressions. It is inappropriate for listing a sequence of equations, as in the case of the Chinese Remainder Theorem. In that case, the "align" environment is the correct environment to use. I reverted your edits that changed the align environment to the cases one because of that. Magidin (talk) 17:01, 23 July 2018 (UTC)[reply]

You ring please. I should have written about it. I would correct the changes. Best regards, Alpha-Gamma (talk) 17:22, 23 July 2018 (UTC)[reply]

I'm sorry, but I do not understand what "You ring please" is supposed to mean. In any case, I went ahead and made the corrections myself, and just wanted to alert you as to the reason why I did this, so you would not go back and change it back. Magidin (talk) 18:35, 23 July 2018 (UTC)[reply]

No, it's not better. The point is to not have the left curly bracket before the equations. That bracket is unnecessary, out of place, and is not used to display systems of equations. That is why I changed your typesetting. To take out, to remove the left curly bracket that you insist on putting on the left side of the display. That's the whole point. Trust me on this; I'm a published author of mathematical papers. That bracket does not belong there. Magidin (talk) 20:40, 23 July 2018 (UTC)[reply]

HTML to Latex conversion

Thank you for your edits of Residue number system‎‎, which consist, mainly, in converting html to latex. Such a systematic conversion is discouraged by MOS:FORMULA. Also, using Latex for single variables and simple inline formulas is not recommended, because of bad horizontal alignment of the present Wikipedia implementation of Latex. On the other hand, I agree that the use of a sanserif font for math is problematic, as the rendering of html and latex are very different. Thus for edits like yours, most mathematics editors prefer using {{math}} template. Moreover, it is easier to use it than converting to latex: select the formula, and use the button {{math}} in the "Math and logic" menu (be care that if = appears in the formula, then 1= must be added before the formula, just after |).

Thanks a lot for remarks. This information for me new. With the best ... Alpha-Gamma (talk) 10:57, 29 July 2018 (UTC)[reply]
