Which of the following sentences regarding the calculation of something should be preferred?

- The calculation of the result
bythis equation…- The calculation of the result
by means ofthis equation…- The calculation of the result
throughthis equation…- The calculation of the result
fromthis equation…Moreover, is any of them particularly incorrect?

**Answer**

As a matter of style, I would write “The calculation of the result *through the use of* this equation”. Alternatively I would suggest *by the use of*.

The correctness of choosing *by*, *by means of*, *through*, or *from* depend on whether *this equation* is thought of as a tool, a route to a result, or a process that generates a result. The choice of the phrase *through the use of* avoids any ambiguity about the nature of *equation* because it is equally applicable to all of those meanings.
