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)
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.

k Overflow and Errors
Exceeding a specified input or calculation range, or attempting an illegal input causes an error
message to appear on the display. Further operation of the calculator is impossible while an
error message is displayed. For details, see the “Error Message Table” on page α-1.
• Most of the calculator’s keys are inoperative while an error message is displayed. Press J
to clear the error and return to normal operation.
k Memory Capacity
Each time you press a key, either one byte or two bytes is used. Some of the functions that
require one byte are: b, c, d, sin, cos, tan, log, In, ' , and π .
Some of the functions that take up two bytes are d / dx (, Mat, Vct, Xmin, If, For, Return,
DrawGraph, SortA(, PxIOn, Sum, and a
n
+1
.
• The required number of bytes to input functions and commands is different in the Linear
input/output mode and the Math input/output mode. For details about the number of bytes
required for each function in the Math input/output mode, see page 1-11.
