When I have two numbers and they are the same, we can say that they possess "equality".
Let's say I have three or four numbers and they are all the same. What do we call the quality that they possess? Can we say that the three numbers possess "equality" too? What are the other words for this quality?
For example, I have four numbers 4, 4, 4, and 4. What quality do these numbers exhibit?
Thank you!
