Answer:
Commutative property of addition
Explanation:
A set S is said to be commutative under addition if :
![\begin{gathered} \forall a,b\in S \\ a+b=b+a \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/37gqdlq238i7i8d1xbzr9747mpnwoo8ccq.png)
Thus, given the operation:
![1.8+7.3=7.3+1.8](https://img.qammunity.org/2023/formulas/mathematics/college/uxywcdap3c8v2ve111c3lqk3thihe0zkt6.png)
The property being illstarated is the commutative property of addition.
What this means is that when adding two numbers or variables, the order of the placement of the numbers/variables does not matter as the same resut will be obtained.
