Distinctions made in writing are often not made explicit in speech; thus the sounds fx /'ef eks/ may be interpreted as any of: fx, fl(x), f^, FX, FX. The difference is usually made clear by the context; it is only when confusion may occur, or where he wishes to emphasise the point, that the mathematician will use the longer forms: f multiplied by x, the function of x, f subscript x, line FX, vector FX. 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"-l and a"-1 The most common pronunciations are given in the list below.
