Use of Technology in Math 0470
Calculators are not allowed for use on exams or quizzes in math 0470.
In all Mathematics courses, students with a documented learning disability
that specifically requires a calculator as determined by Health Services, will
be allowed to use a basic calculator for all test/quiz questions where
arithmetic calculations are not the main objective. The specific disability must
be verified with Health Services before the accommodation can be made.
