SETS OF NUMBERS

**Sets Of Numbers –**

**You are familiar
with the following infinite sets of numbers.**

**1) Set N of
natural numbers, i.e., N = {1, 2, 3,……………}**

**2) Set W of
whole numbers, i.e., W = {0, 1, 2, 3, ………….}**

**3) Set Z of
integers, i.e., Z = {………….., -3, -2, -1, 0, 1, 2, 3,………………..}**

**5) The set of
irrational numbers, such as √3 and π, which cannot be expressed as a quotient
of two integers, and their decimal forms do not terminate or repeat. However, we
can approximate these numbers using terminating decimals, e.g., √2 = 1.414, π =
3.14, √3 = 1.732**

** -7√5, π, e, √8,
√3/2**

**6) The set of
real numbers R includes all the above sets of numbers.**
