Inputting Expressions and Values
Basic Input Rules
Calculations can be input in the same form as they are written. When you press the priority sequence of the input calculation will be evaluated automatically and the result will appear on the display.

*1 Input of the closing parenthesis is required for sin, sinh, and other functions that include parentheses.
*2 These multiplication symbols (σ) can be omitted. A multiplication symbol can be omitted when it occurs immediately before an opening parenthesis, immediately before sin or other function that includes parentheses, immediately before the Ran# (random number) function, or immediately before a variable (A, B, C, D, E, F, M, X, Y), scientific constants, Π or e.
*3 The closing parenthesis immediately before the operation can be omitted.

Note: • If the calculation becomes longer than the screen width during input, the screen will scroll automatically to the right and the ; indicator will appear on the display. When this happens, you can scroll back to the left by using B and C to move the cursor. • When Linear Display is selected, pressing Dwill cause the cursor to jump to the beginning of the calculation, while A will jump to the end. • When Natural Display is selected, pressing C while the cursor is at the end of the input calculation will cause it to jump to the beginning, while pressing B while the cursor is at the beginning will cause it to jump to the end. • You can input up to 99 bytes for a calculation. Each numeral, symbol, or function normally uses one byte. Some functions require three to 13 bytes. • The cursor will change shape to Iwhen there are 10 bytes or less of allowed input remaining. If this happens, end calculation input and then press .
Calculation Priority Sequence
The priority sequence of input calculations is evaluated in accordance with the rules below. When the priority of two expressions is the same, the calculation is performed from left to right.
