Binary Operation

A Binary Operation takes two elements and produces a third element.

2+3 = 5

Does it make sense in the next format?

ScalarAddition(2,3) = 5

Appendix A

Later you’ll run into discussions with words like n-ary. Binary is when n=2.

Appendix B

You might be dealing with an operation, using the symbol * and they write something like

X * X –> X

In this case the X represents the set containing the elements used. For our first example, that could be the set X={2,3,5}.
