Prove or disprove that if m and n are integers such that mn = 1 then either m= 1 & n = 1 or else m = -1 & n = -1.

Real Analysis is a branch of mathematics that deals with the study of real numbers and their properties. It focuses on understanding the behavior and properties of real-valued functions, sequences, and series.
This statement is commonly known as the "inverse property of multiplication" and it means that if the product of two real numbers is equal to 1, then those two numbers must be either 1 or -1.
The statement is related to Real Analysis because it involves the manipulation and understanding of real numbers and their properties. It is often used in proofs and demonstrations within the field of Real Analysis.
To prove this statement, we can use the axioms and properties of real numbers, such as the commutative, associative, and distributive properties of multiplication, along with the definition of the multiplicative inverse. We can also use logical reasoning and algebraic manipulation to show that the statement holds true.
The inverse property of multiplication has many practical applications, such as in engineering, physics, and economics. For example, it is used in calculating the resistance of electrical circuits, determining the velocity and acceleration of objects in motion, and in calculating the exchange rates of currencies.
