Taking into account the irrational numbers and the real numbers, ourclassification might look like this:
Figure %: Classification of Numbers If a number falls into a category, it also falls into all the categories belowthat category to which it is connected by a line. For example, 7 is aninteger, so it is also a rational and a real number. The square root of 2is an irrational number, so it is also a real number.
