Binary Operations, Finite Arithmetic and Groups,the set is said to be closed for the operation. In other words, a binary operation combines two elements of a set to form a single element of the set. Examples of binary operations already met in earlier chapters include.Subtraction is not a binary operation on the set of natural numbers, since subt

Further Plane Geometry,xioms and a series of theorems, each of which is proved by reference to those earlier in the series. In this chapter a formal statement is made of some important theorems, with examples to show how they are applied to problems in geometry. In solving such geometrical problems any appropriate method,
