The number of elements in the set.

. In mathematics cardinal numbers or cardinals for short are a generalization of the natural numbers used to measure the cardinality size of setsThe cardinality of a finite set is a natural number. Also the decimal expansion of an irrational number is neither terminating nor repeating. A rational number is a kind of real number with the formula mn where n 0.

But let us consider another example 342 -42 the sum is 3 which is a rational number. So we should be very careful while adding and multiplying two irrational numbers because it might result in an irrational number or a rational number. The transfinite cardinal numbers often denoted using the Hebrew symbol followed by a subscript describe the sizes of infinite sets.

For example if we add two irrational numbers say 3 2 43 a sum is an irrational number. Lets see if the same thing is true for the sum of two rational numbers. So lets say my first rational number is ab or can be represented as ab and my second rational number can be represented as mn.

These numbers are written as pq where p and q are integers and q zero. Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction pq where p and q are integersThe denominator q is not equal to zero q 0. When a rational number is divided the outcome is a decimal number which can be either ended or repeated.
