Is "A ディバイディッド・バイB イコールC" the correct Katakana translation of "A ÷ B = C"?


Is "A ディバイディッド・バイB イコールC" the correct Katakana translation of "A ÷ B = C"?




This question is a little more interesting than it seems because convention vs
pronunciation is always an issue when discussing the choice for
transliteration of foreign words.

"Equals", as in A+B _equals_ C, is pronounced with voiced s, so it should
probably transliterated as イコールズ. However plain イコール is sometimes used in
Japanese language too, both in mathematics and in figurative usages. Both is
possible, but イコールズ might indicate that you do care about the actual
pronunciation (ref. 原音主義).

Divided is pronounced with -/id/, so it would most naturally be transliterated
with ディバイディッド. For this word there's no established convention either.
However, we somehow tend to be tricked by the spelling --- one famous being
money vs マネー --- and some people might choose ディバイデッド instead. Actually, the
game "Deus Ex: Mankind Divided" is sold under the label of [デウスエクス
マンカインド・ディバイデッド](https://www.jp.square-enix.com/deusex/top.html).

In this case the choice is yours (I, for one, am eager to endorse the original
pronunciation: thus I'd use ディバイディッド and イコールズ). イコール might sound more natural
as Japanese. Using イコールズ and ディバイデッド alongside can be inconsistent.

Edit: I didn't recognize your comment in the question. For teaching English
learners how to read the equation, definitely use イコールズ and ディバイディッド. However
it would be more beneficial for them to avoid katakana at all, because they'll
soon be stuck with multiple difficulties. Refer, for example, [the oxford
dictionary](https://www.oxfordlearnersdictionaries.com/definition/english/divided?q=divided)
for a sensible style for expressing the pronunciation. If they're learning
English, let them learn in English, rather than having them mimick it.
