<p>I guess one of the difference(s) is that 方程 can be used without situation of math (e.g. &quot;I will use this grammatical equation of Chinese&quot;) but 方程式 is mostly used in mathematical expression(e.g. &quot;Equation for the cube roots of 1&quot;).</p>

Both 方程 and 方程式 can be read as "(mathematical) equation" so I am confusing the difference(s) between it.

I guess one of the difference(s) is that 方程 can be used without situation of math (e.g. "I will use this grammatical equation of Chinese") but 方程式 is mostly used in mathematical expression(e.g. "Equation for the cube roots of 1").

How actually?

方程 is equation/formula. 方程式 is listed in the dictionary as an alternate form of 方程. So there is no inherit difference in meaning, its just a matter of which you encounter more frequently. I do think you are unlikely to encounter 方程式 in the names of formulas, since those are nouns themselves and not people choosing vocab casually, if that makes sense.

If not sure which to use, I think it would be safe to stick with the standard 方程。

方程 is equation

方程式 is expression

公式 is formula

Those Chinese words are sometimes used as synonyms, just as the Engilish words.
