Our exams have been created in a way that we hope no calculator is needed. However, we do understand on many math exams they serve as a comfort even for double checking simple mental math. Any non-graphing calculator is acceptable (a graphing calculator is anything that can complete formulas for you or produce anything other than solutions to equations).
You are now provided an online scientific calculator in final exams.You'll see a link in the exam that allows you to open an approved window. If you want to get familiar with the functionality of the calculator before the exam (which is a great tip!), check it out here. Note that only the scientific version of this calculator is allowed. If you use a graphing calculator, your exam will be invalidated.
A computer or cell phone calculator is not allowed as we cannot verify what other information may be accessed using those devices.
