Section 2.1 Practice Exercises Study Skills Exercise After getting a test back, it is a good idea to correct the test so that you do not make the same errors again. One recommended approach is to use a clean sheet of paper, and divide the paper down the middle vertically as shown. For each problem that you missed on the test, rework the problem correctly on the left-hand side of the paper.Then give a written explanation on the right-hand side of the paper.To reinforce the correct procedure, do four more problems of that type. Take the time this week to make corrections from your last test. Vocabulary and Key Concepts 1. a. An is a statement that indicates that two expressions are equal. b.
