FX . The di?rence is usually made clearby the context; it is only when confusion may occur, or where he/she wishes to emphasisethe point, that the mathematician will use the longer forms: f multiplied by x, the functionf of x, f subscript x, line FX, the length of the segment FX, vector FX.Similarly, a mathematician is unlikely to make any distinction in speech (except sometimesa di?rence in intonation or length of pauses) between pairs such as the following: x + (y + z) and (x + y) + zpax + b and pax + ban ?1 and an?。
