Question

What operations are defined for any two real numbers?

Answer 1

For the mathematical system that consists of the set of real numbers together with the operations of addition, subtraction, multiplication, and division, the resulting properties are called the properties of real numbers.

Closure Property of Addition also holds in real numbers: The sum of two real numbers is a real number.

multiplication pairs any two real numbers with a real number to become a product a×b

for all real numbers a and b, the difference denoted as a - b is defined by: a - b = a + (-b).

Hence we can also apply the BODMAS rule to the real numbers.
