k Inputting with Math Format
When inputting with Math format, you can input and display fractions
and some functions using the same format as they appear in your
textbook.
Important!
• Certain types of expressions can cause the height of a calculation
formula to be greater than one display line. The maximum allowable
height of a calculation formula is two display screens (31 dots
× 2).
Further input will become impossible if the height of the calculation
you are inputting exceeds the allowable limit.
• Nesting of functions and parentheses is allowed. Further input will
become impossible if you nest too many functions and/or
parentheses. If this happens, divide the calculation into multiple
parts and calculate each part separately.
Functions and Symbols Supported for Math Format

• The “Bytes” column shows the number of bytes of memory that
are used up by input.
