  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),  π  or  
e .

The closing parenthesis immediately before the  = operation can be omitted.

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) é 6 ÷ (2 (1 + 2))   6 ÷ A (1 + 2) é 6 ÷ (A (1 + 2))
  1 ÷ (2 + 3) sin(30) é 1 ÷ ((2 + 3) sin(30))
• When a multiplication sign is omitted immediately before a variable, a 
constant, etc.
  6 ÷ 2π é 6 ÷ (2π)
2 ÷ 2'2 é 2 ÷ (2'2)
4π ÷ 2π é 4π ÷ (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.
