A irrational number times another irrational number can be irrational or rational. For example, √2 is irrational. But: √2 • √2 = 2. Which is rational. Likewise, π and 1/π are both irrational but: π • (1/π) = 1. Which is rational. However, an irrational number times another irrational number can also be irrational:

Numbers in R can be divided into 3 different categories: Numeric: It represents both whole and floating-point numbers. For example, 123, 32.43, etc. Integer: It represents only whole numbers and is denoted by L. For example, 23L, 39L, etc. Complex: It represents complex numbers with imaginary parts. The imaginary parts are denoted by i. So if we add two operands which are natural numbers a and b, the result will also be a natural number. The same holds good for real numbers. Hence, + : R x R → R is given by (a, b) → a + b + : N x N → N is given by (a, b) → a + b.
