Wednesday HW/Quiz Tomorrow!

Tomorrow we will start class with a (15 minute) quiz about matrices:

• Adding matrices 
• Subtracting matrices 
• Multiplying a matrix by a scalar (constant)
• Determining the order of a matrix
• Identifying a square matrix or column matrix or row matrix
• You will also have to explain how to add, how to subtract, and how to multiply by a scalar in your own words!

Tonight's homework = studying for tomorrow's quiz! 

Tonight please complete the following in your matrices problem set (provided in class today) or in our PDF textbook:

Section 8.1 (page 582): 1, 3, and 5

Section 8.2 (page 597): 5, 7, 13, 15 (*For 15 you will have to distribute, then subtract)

If you're feeling ambitious, here's tomorrow night's homework as well--some practice with multiplying matrices! (There will not be any multiplication of matrices on tomorrow's quiz):

Section 8.1 (page 582): 93

Section 8.2 (page 597): 17, 27, 29, 31, 45

Always be sure to check your answers--that's why the answers to the odd problems are provided (and that's why I give you odds for homework)! There's no point in practicing if we're practicing incorrectly!
