Lindsay is writing a persuasive paper on the use of calculators on exams. Which sentence, if added to her paper, would best support her claim that calculators should be allowed for use during exams? Calculators provide students with confidence when taking their exams. Calculators do not allow teachers to adequately assess whether their students know the material that was presented on the exam. Although useful, calculators do not support students' ability to retain vital mathematical information. Most would agree that calculators inhibit students' ability to perform simple mathematical skills.
