• You can select the equality symbol or inequality symbol from the
menu that appears when you press (VERIFY).
3. To verify, press .
You can input the following expressions for verification in the VERIFY
Mode.
• Equalities or inequalities that include one relational operator 4 = √16, 4 ≠
3, π > 3, 1 + 2 ≦ 5, (3 × 6) < (2 + 6) × 2, etc.
• Equalities or inequalities that include multiple relational operators 1 ≦ 1
< 1 + 1, 3 < π < 4, 2
2
= 2 + 2 = 4 < 6, 2 + 3 = 5 ≠ 2 + 5 = 8, 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.
•
An expression with nothing on the left side or right side (Example: =
5√7)
