Home screen
On the Home screen, you can enter mathematical expressions and functions, along with other instructions. The answers are displayed on the Home screen. The TI-30X Plus MultiView™ screen can display a maximum of four lines with a maximum of 16 characters per line. For entries and expressions of more than 16 characters, you can scroll left and right (ⓘ and ⓪) to view the entire entry or expression. In the MathPrint™ mode, you can enter up to four levels of consecutive nested functions and expressions, which include fractions, square roots, exponents with ˆ, ˜, ˜y, eˣ, and 10ˣ.
When you calculate an entry on the Home screen, depending upon space, the answer is displayed either directly to the right of the entry or on the right side of the next line.
Special indicators and cursors may display on the screen to provide additional information concerning functions or results.
