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
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),

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.

• 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.
