The addition postulate, also known as the addition axiom, is a fundamental principle in mathematics that states that for any two numbers, the sum of their quantities remains the same regardless of the order in which they are added.
- In symbolic terms, it can be expressed as "a + b = b + a," where 'a' and 'b' are any real numbers.
- This principle forms the basis of addition and is a fundamental concept in arithmetic and algebra.
