FAQ

What math classes are offered at TCC?

View TCC math course descriptions, technical math course descriptions, or MARC (Tools for Success in arithmetic and algebra) courses in the online catalog. Please note that course numbers with "&" are from the common course numbering system. You can view a flowchart of TCC math classes as well as course recommendations for chosen areas of study is available at the MARC web page.

What's the difference between MARC classes, SI (Supplemental Instruction) classes and Math 10?

MARC classes are 2-credit support classes taken in conjunction with a Math class. Supplemental Instruction (SI): Certain sections of math classes have a student tutor “SI Leader” who attends class every day and meets with students outside of class to provide extra math help. Math 10 is a 4-week, 2-credit individualized intensive review of arithmetic and algebra topics based on the assessed need of students. A detailed chart comparing the three options is available in pdf format.

What Is the Math Advising and Resource Center?

The Al-Khwarizmi Math Advising and Resource Center (or MARC or simply "math center") is located in building 19, room 22. It is a place where students can go to check out calculators, study, get math tutoring, get advice on what math class to take, and more. Please see the Math Advising and Resource Center website for more information.

What calculator should I buy?

Which calculator you need depends on what class you are taking. Below is a class-by-class list of what calculators are recommended by the math department.

  • Math 75: A basic four-function calculator is required. You might find it helpful to have a calculator with a "fraction" key. Calculators are not allowed in all parts of this class, so you should consult with your instructor.
  • Math 85: A scientific calculator is required. The TI-30X IIS is recommended. A scientific calculator has buttons marked "SIN", "COS", and "TAN" on it. You won't use these particular buttons in this class (or in 90), but they are a good way to identify the type of calculator you need. Calculators may not be allowed for some parts this class, so you should consult with your instructor.
  • Math 90 or 95: A scientific calculator is required. (See Math 85 for how to identify one.) The TI-30X IIS is recommended. You should not expect to use a graphing calculator in these classes, as it is department policy that they cannot be used on tests at this level.
  • Math 107: A scientific calculator is recommended. See Math 85 for how to identify one.
  • Math&146: A TI-83/TI-84+ graphing calculator is required. If you have a different graphing calculator, consult the instructor to see if it can be used.
  • Math 147 or Math& 148: Graphing calculator required. The TI-84+ Silver Edition is strongly recommended for its built-in financial functions. Your instructor will demonstrate the TI-84+ in class, but may not demonstrate any other calculators. There is also a guide to use of the TI-83 for Math 147 available. (NOTE: The keystrokes for the TI-83 and the keystrokes for the TI-84 series are identical.)
  • Math& 141 or Math& 142: Graphing calculator required. The TI-84+ Silver Edition is strongly recommended.
  • Math& 151, Math& 152, or Math& 153: Graphing calculator required.The TI-84+ Silver Edition is strongly recommended.
  • Math 220, Math & 254, or Math 238: Graphing calculator probably required. Consult your instructor to be sure and for recommendations.

Can I rent a graphing calculator?

If you are enrolled in a math class that requires the use of a graphing calculator, you may rent one for $20 on a first-come-first-served basis. For detailed information, stop by the MARC in Bldg. 19, Room 22.

How do I use my graphing calculator?

If you use the recommended calculator for your class, your instructor should be able to help you learn how to use it. Additional help is available for some types of calculators by following the links below. Note that guides are in pdf format. You need the FREE Adobe Acrobat Reader to view them.

  • A Quick Introduction to the TI-83 (V. 1.0) provides a brief, non-course-specific introduction to the TI-83. This file is 471KB.
  • Using the TI-83 in Math 147 (V 1.3) is a guide written specifically for Math 147 students. This file is 555KB. Note: This guide is no longer updated. It is recommended that you use a TI-83+ or TI-84+ in Math 147. (See below.)
  • Using the TI-83+/TI-84+ in Math 147 (V 1.0) is a guide written specifically for Math 147 students. The guide is also sold in the TCC bookstore. This file is 344KB.
  • A Quick Introduction to the TI-86 (V. 2.0) provides a brief, non-course-specific introduction to the TI-86. This file is 486KB.
  • The title of An Introduction to Solving Systems of Equations Using Matrices and the TI-86/89 Calculators for Physics and Engineering Students is pretty self-explanatory. This guide assumes that you are generally familiar with your graphing calculator. This file is 54KB.
  • For additional help with the TI-81, 82, 83, 84, 85, 86, 89 and 92 and the HP-48G or 49G, contact David Straayer.
