Examples: See the “Examples” page for problems with
keystroke sequences that demonstrate many of TI-10
functions and capabilities. Before starting each problem set,
reset and clear the TI-10 by pressing b”. This helps to
ensure that your displays are the same as those shown in
the examples. In Problem Solving AUTO mode, however,
displays will vary from those shown in the examples
because the problems presented by the TI-10 are random.
