You can store any TI InterActive! data type as a variable. Some
examples are:
Data type Examples
Expression
2.54
List {2, 4, 6, 8}
[
Matrix
1 2 3
3 6 9
Character string "Hello"
Function myfunc( arg )
To enter several statements in a single Math Box, separate them
with pairs of colons. Only the result of the last expression is
shown.
You can delete TI InterActive! math objects (such as Math Boxes,
lists, and graphs), and you can drag them to a different position
on the page. However, deleting or moving an object can cause
results to change in the objects that follow it.
That's because variables persist from one math object to another.
The physical positions of the objects determine the order in
which they are processed by the TI InterActive! math system. The
"math flow" is identical to the reading pattern: left-to-right along
each line of a paragraph, and top-to-bottom between paragraphs.
