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.
