Please hold up your TI 83/ TI 84 calculator to the camera and hold it there for 5 seconds. You can not have a case on the calculator.   This is the only calculator approved by the math department for this course.  If you do not want to purchase the TI 83/ TI 84 calculator, a 4 function basic  nonscientific calculator can be used (all a basic calculator can do is add, subtract multiply and divide).   Once you have held up your approved calculator, click on true.  If you do not have an approved calculator, please submit the exam and contact me to reopen the exam once you have purchased your approved calculator.  Do not click true when you do not have an approved calculator – that is academic dishonesty.
