• WebAssign Students in Math 120 are required to use WebAssign for homework assignments. You will need to purchase an access code (between $50 and$60). After the start of the quarter, you can log in to WebAssign here and purchase an access code on the WebAssign website. This will require your UW Net ID. Your UW Net ID is the part of your university email address before the @ symbol. The password to log in is your UW Net ID password.

You must be enrolled in the course in order to get access to the homework on WebAssign.

• There is a required calculator for Math 120, 124, 125 and 126. It is the Texas Instruments TI-30X IIS which can be purchased from many places for well under \$20. The UW Bookstore carries orange ones, which they will buy back at the end of quarters, but any color is acceptable for Math 120, 124, 125 and 126. Here is a picture of a black (the most common color) TI-30X IIS for reference.
