*The teacher said to the student,*

*"Multiply *\(3 \times 7\)*."*

*The teacher announced to the students that were going to be learning about operations.*

*The students didn't understand. This was a mathematics class. They didn't want to do operations. That was for doctors to learn.*

*The teacher said, "You do operations in this class all the time."*

*"WE DO?" answered the puzzled students.*

*Now they were a little skeptical.*

*But they were a little curious, too.*

*When they went home that night, they proudly told their parents that they performed operations in school.*

*Most parents looked at each other and smiled weakly.*

- 7.1: Operations and Properties
- This exercise set is designed to give you an understanding of what "binary operations" are, and to give you a deeper understanding for the commutative, associative and distributive properties. To do this, we're going to define and work with some nonsense operations.
