k Multiplication Operations without a Multiplication Sign
You can omit the multiplication sign ( × ) in any of the following operations.
• Before Type A functions ( 1 on page 2-3) and Type C functions ( 6 on page 2-3), except for
negative signs
Example 1 2sin30, 10log1.2, 2
'
3
, 2Pol(5, 12), etc.
• Before constants, variable names, memory names
Example 2 2 π , 2AB, 3Ans, 3Y
1 , etc.
• Before an open parenthesis
Example 3 3(5 + 6), (A + 1)(B – 1), etc.
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.
Example 1 6÷ 2(1 + 2) → 6 ÷ (2(1 + 2))
6 ÷ A(1 + 2) → 6 ÷ (A(1 + 2))
1 ÷ (2 + 3)sin30 → 1 ÷ ((2 + 3)sin30)
• When a multiplication sign is omitted immediately before a variable, a constant, etc.
Example 2 6 ÷ 2π → 6 ÷ (2π)
2 ÷ 2'2 → 2 ÷ (2'2)
4π ÷ 2π → 4π ÷ (2π)
