### Old Announcements

Second Midterm early option. Some of you have a Chemistry midterm right after the Math 2030 midterm on Monday. We will allow a group of students to start the Math midterm 10 minutes early, at 9:25, and finish 10 minutes early, at 10:15. If you would like to take advantage of this early option, please be there at 9:20 so that those leaving early can all be seated together. Everyone else will take the midterm from 9:35-10:25 as usual.

Second Midterm. The second midterm will be in class on Monday, March 10. It will focus on sections 2.3-2.4 and 3.1-3.3. Although the second midterm does not specifically focus on the older material covered on the first midterm (sections 1.1-1.3 and 2.1-2.2), you will still have to know it of course. In Section 2.4, you only need to know the application we did in class (finite linear games). Here are some practice problems:

• 2.3 #3, 8, 11, 17, 23, 25, 26, 33, 35, 36, 42.
• 2.4 #3, 31.
• 3.1 #13, 19, 23, 35.
• 3.2 #5, 15, 23.
• 3.3 #9, 11, 23, 25, 35, 43, 53, 62.
