1 + 1 = 2

A statement expressing that the sum of 1 and 1 equals 2. It's a fundamental principle in mathematics.

Closed System

A set of numbers where the result of an operation on its members remains within the set. For example, the sum of two natural numbers is always another natural number.

Mathematical Identity

A mathematical statement that is always true, regardless of the values of the variables involved.

Binary Operation

A mathematical operation that combines two numbers (operands) to produce a single number. For example, addition, subtraction, multiplication, and division.

Study Notes

Mathematical Identity

The statement "1 + 1 = 2" represents a fundamental mathematical assertion.
It expresses the addition of the natural numbers 1 and 1, resulting in the natural number 2.
This equation is a basic example of arithmetic and a cornerstone of number systems.
The equation holds true in all common number systems, including natural numbers, integers, rational numbers, real numbers, and complex numbers.
It is an example of a closed system where the result, 2, is a member of the same set of numbers as the operands (1 and 1).
This equation is easily demonstrated with concrete objects (e.g., counting two apples).
The result is consistent across different contexts and disciplines relying on basic number theory.
The equation signifies a binary operation inherent in arithmetic. l
