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 is not allowed if the height of the calculation exceeds the limit.

•You can nest functions and parentheses. However, if you nest too many functions and/or parentheses until input is no longer permitted, divide the calculation into multiple parts and calculate each part separately.

Functions and Symbols Supported for Math Format Input

The Bytes column shows the number of bytes of memory used during input.

Function/Symbol	Key Operation	Bytes
