¢ You can select the equality symbol
or inequality symbol from the menu
that appears when you press
(sHiFt) (2) (VERIFY).
. To verify, press (E).

You can input the following expressions for verification in the VERIFY
Mode.
¢ Equalities or inequalities that include one relational operator 4 = V16,
44#3,n>3,1+2 55, (8x6) < (2+ 6) x2, etc.
* Equalities or inequalities that include multiple relational operators 1 =1<1+1,
3<n< 4, 27=24+2=4,2+2=4<6,24+3=5#42+5=6, etc.
Note: ¢ The verification result will cause 1 to be assigned to Ans memory
when TRUE and 0 when FALSE. « The input expression can be a total of
99 bytes, including the left side, right side, and relational operators. * Any
variable (A, B, C, D, E, F, X, Y, M) input into an expression is treated as
a value, using the value currently assigned to the variable. * Pol and Rec
functions cannot be used in an expression.
In the VERIFY Mode, the calculator performs a mathematical operation
on the input expression and then displays TRUE or FALSE based on the
result. Because of this, calculation error can occur or a mathematically
correct result may not be able to be displayed when the input calculation
expression includes calculation that approaches the singular point or
inflection point of a function, or when the input expression contains multiple
calculation operations.
Expression Input Precautions
The following types of expressions cause a Syntax ERROR and cannot
be verified.
e An expression with nothing on the left side or right side (Example: = 5v7)
¢ An expression in which a relational operator is inside of a fraction or function
(Example: 1 =1, cos (8 = 9))
2
e
An
expression
in
which
a
relational
operator
is
enclosed
in
parentheses
(Example:

10))
*
An
expression
in
which
multiple
relational
operators
that
are
not
oriented
in the
same
direction
(Example:
5
=
6

4)
¢ An expression that contains two of the following operators in any combination
(Example: 4 < 6 # 8)

(Example: 5 2 > 9)
