Using
¹
and
Ì
Many graphing handhelds (including the TI-84 Plus) make a distinction
between the symbols for subtraction and negation.
Use ¹ to enter subtraction operations. Use Ì to enter a negative
number in an operation, in an expression, or on a setup screen.
Example: Subtract 10 from 25.
Example: Add 10 to L25.
Example: Subtract L10 from 25.
Note: Notice that the TI-84 Plus displays a slightly different symbol for
negation and subtraction to make it easier for you to distinguish
between the two. The negative symbol is raised and slightly shorter.
