Operating the TI-80 1-7
To enter a number in scientific notation:
1. Type the part of the number that precedes the exponent.
This value can be an expression.
2. Press 2 ^. í is displayed.
3. If the exponent is negative, press ·, and then type the
exponent, which can be one or two digits.
Entering a number in scientific notation does not cause the
answers to be displayed in scientific notation. The display
format is determined by the mode settings (pages 1-9 through
1-11) and the size of the number.
A function returns a value. For example, ÷, ×, −, +, ‡, and LOG
are functions. Some functions take more than one argument,
which is indicated by a ( at the end of the name. MIN( requires
two arguments in this example: MIN(5,8).
An instruction initiates an action. For example, CLRDRAW is
an instruction that clears any drawn elements from a graph.
Instructions cannot be used in expressions. Some instructions
take more than one argument, which is indicated by a ( at the
end of the name. LINE( requires four arguments in this
example: LINE(1,1,3,3).
While the busy indicator is displayed, indicating that a
calculation or a graph is in progress, you can press ´ to stop
the calculation. (There may be a delay.)
