  2. What calculators can be used for ACT or SAT?
    You can go to the following page for information on what calculators are acceptable for ACT:
    The page doesn't specify which models are acceptable, although it does specify some models that are not acceptable. For the most part, it presents guidelines as to what types of functions would not be acceptable.
    Similar information regarding calculators that are acceptable for SAT can be found at the following page:
  3. Is there any supplementary material for the graphing calculators?
    Here are two resources that discuss examples of applications that our calculators may be used for.

    You can transfer the programs and materials (e-Activities) of the ClassPad made using a personal computer/ClassPad to the ClassPad using ClassPad Manager.
  5. What tests are calculators permitted for?
    AP Calculus requires a graphing calculator.
    Any graphing or scientific calculator is permitted on the following as long as it does not have a QWERTY keyboard, electronic writing pad or a pen-input/stylus-driven interface:
    SAT II Math, IC & IIC
    AP Statistics (graphing expected)
    AP Chemistry
    AP Physics
    See for more information.
    For the GED, the FX-260 Solar is suggested.
  6. Why do I keep getting an error message when I try to perform arithmetic or trigonometric calculations?
    The error messages should indicate what the problem is. See the error message list in your calculator's user's guide for more information.
    For example:
    Ma ERROR or Math ERROR
    Cause: The calculation result is outside of the allowable calculation range or you are trying to perform an illegal mathematical operation (such as division by zero).
    Action: Check your input values and adjust them to allow the calculation result to be within the allowable range. If you are using memory for your calculation, make sure that you check the memory value.
    Syn ERROR or Syntax ERROR
    Cause: The calculation expression is the wrong syntax, or the program you are using contains a syntax error.
    Action: Press the or key to display the location of the error, and correct it.
    Stk ERROR or Stack ERROR
    Cause: The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded.
    Action: Simplify your calculation expression. You could also split your calculation expression into two or more parts and execute the parts separately.
    Mem ERROR
    Cause: You executed a matrix, graphing, or some other operation that caused remaining memory capacity to be exceeded.
    Action: Delete memory data you no longer need. Make sure that the number of variables used in your expression does not exceed the number of variables that are available.
    Other error messages may appear to let you know that a calculation you are trying to perform is not compatible with your current mode, angle unit, display, or other setting. If this happens, check the setup of your calculator and try again.
  7. What is an overflow error?
    Whenever the integer part of a calculation result is longer than the maximum number of digits that the calculator can display, you will receive an Overflow Error. The result will be presented as a rounded number. (Please refer to the question "What is a Round Number Calculation" for more information.)
  8. My PRIZM calculator displays my answers as a fraction. How can I change it to display a decimal answer?
    If you would like to change the last answer to a decimal, simply press the button, located right above the button. The button (Form to Decimal) is a toggle switch and will switch between a fractional answer and it’s decimal form. This button will also change any answer in Standard Form to a decimal and vice versa. For example, if you’re answer is 2 , by pressing the button, the calculator will change your answer to its decimal form. Also, using the division button, instead of our fraction button, will display answers as a decimal.
  9. Help! I accidentally erased my Add-in icons (Geometry, Picture Plot, and Conversion)on my Prizm How do I get those back on my calculator?
    Our suggestion, when resetting the calculator, is to reset the Setup Data and/or the Main Memory.
