Distinctions made in writing are often not made explicit in speech; thus the sounds fx may be interpreted as any of: fx, f(x), fx, F X, F X, −−→F X . The difference is usually made clear by the context; it is only when confusion may occur, or where he/she wishes to emphasise the point, that the mathematician will use the longer forms: f multiplied by x, the function f of x, f subscript x, line F X, the length of the segment F X, vector F X. Similarly, a mathematician is unlikely to make any distinction in speech (except sometimes a difference in intonation or length of pauses) between pairs such as the following: x + (y + z) and (x + y) + z √ ax + b and √ ax + b a n − 1 and a n−1 The primary reference has been David Hall with Tim Bowyer, Nucleus, English for Science and Technology, Mathematics, Longman 1980.
