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.
4 × sin30 × (30 + 10 × 3) = 120
4 *s 30 )*( 30 + 10 * 3 )=

* Input of the closing parenthesis is required for sin, sinh, and other functions
that include parentheses.
These multiplication symbols ( × ) can be omitted. A multiplication symbol
2
*
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), π or
The closing parenthesis immediately before the = operation can be

example.
Important: If you execute a calculation that includes both division and
multiplication operations in which a multiplication sign has been omitted,
parentheses will be inserted automatically as shown in the examples below.
• When a multiplication sign is omitted immediately before an open
parenthesis or after a closed parenthesis.
6 ÷ 2 (1 + 2) p 6 ÷ (2 (1 + 2))
1 ÷ (2 + 3) sin(30) p 1 ÷ ((2 + 3) sin(30))
• When a multiplication sign is omitted immediately before a variable, a
constant, etc.
6 ÷ 2π p 6 ÷ (2π)
• When inputting a function that uses commas (such as Pol, Rec, and
RanInt#), be sure to input the closed parentheses required by the
expression. If you do not input closed parentheses, parentheses may not
be inserted automatically as described above.
Important: If you execute a calculation in which a multiplication sign has been
omitted immediately before a fraction (including mixed fractions), parentheses
will be inserted automatically as shown in the examples below.
