Find the absolute value of a number.It cannot be both. The sets of rational and irrational numbers together make up the set of real numbers. As we saw with integers, the real numbers can be divided into three subsets: negative real numbers, zero, and positive real numbers. Each subset includes fractions, decimals, and irrational numbers according to their algebraic sign (+ …Generally, the symbol used to express the irrational number is “P”. The symbol P is typically used because of the connection with the real number and rational number i.e., according to the alphabetic sequence P, Q, R. But in most cases, it is expressed using the set difference of the real minus rationals, such as R- Q or R\Q.The ∊ symbol can be read as an element of or belongs to or is a member of, and this ℚ symbol represents the set of rational numbers. So in order to establish if one is a member of the set of rational numbers or one is not a member of the set of rational numbers, we’ll need to recall what the rational numbers are.

Notation: You can use a dot or a bar over the repeated digits to indicate that the decimal is a recurring decimal. If the bar covers more than one digit, then all numbers beneath the bar are recurring. If you are asked to identify whether a number is rational or irrational, first write the number in decimal form.

The set R of all real numbers is the (disjoint) union of the sets of all rational and irrational numbers. We know that R is uncountable, whereas Q is countable. If the set of all irrational numbers were countable, then R would be the union of two countable sets, hence countable. Thus the set of all irrational numbers is uncountable. #6 Let N be ...
