The equation \( 1 + 1 = 2 \) can be explained using basic principles of arithmetic and the properties of the number system.

1. **Definition of Addition**: Addition is the process of combining two numbers to get a sum. When you add 1 to another 1, you are essentially combining two single units.

2. **Number Line Concept**: On a number line, if you start at 1 and move one step to the right, you land on 2. This visual representation helps in understanding the concept of adding 1 to 1.

3. **Peano Axioms**: These are a set of axioms for the natural numbers proposed by Giuseppe Peano. According to these axioms:
   - There is a natural number 0.
   - Every natural number has a successor, which is also a natural number.
   - 1 is defined as the successor of 0, and 2 is the successor of 1.
   - By this, adding 1 (the successor of 0) to 1 results in 2 (the successor of the successor of 0).

4. **Basic Counting**: When you count objects, starting with one object and adding another gives you two objects. This practical approach helps in visualizing and understanding the concept.
