When youpress the priority sequence of the input calculation will be evaluatedautomatically and the result will appear on the display.4 ssin30 s(30 + 10 s3) = 1204 Q 30 30 10 3 *1*2 * 3*1 Input of the closing parenthesis is required for sin, sinh, and other functionsthat include parentheses.*2 These multiplication symbols (s) can be omitted.

Some functionsrequire three to 13 bytes. • The cursor will change shape to I when there are10 bytes or less of allowed input remaining. If this happens, end calculationinput and then press .Calculation Priority SequenceThe priority sequence of input calculations is evaluated in accordance with therules below. When the priority of two expressions is the same, the calculationis performed from left to right.
