 # calculator-class-exercise
+
+
+
+Tasks:
+1. Clone this repo locally
+
+2. Create a NEW local branch. Name it like JC-038-calc, where JC are your initials and 038 is the last three digits
+of your netid. (Or pick three random numbers instead of your netid digits if you prefer.)
+
+git checkout -b JC-038-calc
+
+3. Install pytest if needed.
+
+python -m pip install pytest
+
+4. Create Unit Tests to properly unit test the calculator.py code. You may not change ANYTHING
+in calculator.py. You can only edit test.py. Using pytest is much easier that unittest.
+
+5. Push you local branch to github
+
+git add test.py
+git commit -m "More unit tests"
+git push --set-upstream origin JC-038-calc
+
+6. Submit a pull request (PR) and assign it to me
+
