  • 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.
