    digit limit are displayed in scientific notation.

    Display IndicatorsRefer to Appendix B for a list of the displayindicators.

    Order of OperationsThe TI-30X S uses the Equation OperatingSystem (EOSTM) to evaluate expressions. The

    operation priorities are listed on thetransparency master in Chapter 4, Order ofOperations and Parentheses (page 41).

    Because operations inside parentheses areperformed first, you can useDE to change

    the order of operations and, therefore, changethe result.

    2nd Functions

    Pressing% displays the 2nd indicator, andthen accesses the function printed above the

    next key pressed. For example,%b25E

    < calculates the square root of 25 and

    returns the result, 5.

    MenusCertain TI-30X S keys display menus:z,%h,L,%t,u,

    %w,H,I,%k,=%d,% and%.

    Press! or" to move the cursor and

    Press< while the item is underlined, or

    For menu items followed by an argument

    value (for example, nPr), enter the value

    while the item is underlined. The item andthe argument value are displayed on theprevious screen.

    Previous Entries#$After an expression is evaluated, use# and$ to scroll through previous entries, which arestored in the TI-30X S history. You cannot

    retrieve previous entries while in STATmode.

    Error MessagesRefer to Appendix C for a listing of the errormessages.

    Last Answer (Ans)The most recently calculated result is stored

    to the variable Ans. Ans is retained in memory,

    even after the TI-30X S is turned off. To

    recall the value ofAns:

    Press%i (Ans displays on thescreen), or

    Press any operation key (T,U, etc.) asthe first part of an entry. Ans and theoperator are both displayed.
