Sign-magnitude notation is the simplest and one of the most common methods of representing positive and negative numbers either side of zero, (0).Thus negative numbers are obtained simply by changing the sign of the corresponding positive number as each positive or unsigned number will have a signed opposite, for example, +2 and -2, +10 …Set builder notation is very useful for writing the domain and range of a function. In its simplest form, the domain is the set of all the values that go into a function. For Example: For the rational function, f(x) = 2/(x-1) the domain would be all real numbers, except 1.This is because the function f(x) would be undefined when x = 1.For this reason we say that each real number has an opposite. Opposites are the same distance from zero but have opposite signs. The opposite of a real number is denoted by placing a negative sign directly in front of the number. Thus, if \(a\) is any real number, then \(−a\) is its opposite. Notice that the letter \(a\) is a variable. Thus ...
