3. To verify, press
You can input the following expressions for verification in the VERIFY
Mode.
3, π > 3, 1 + 2 ≦ 5, (3 × 6) < (2 + 6) × 2, etc.
• Equalities or inequalities that include one relational operator 4 = √16, 4 ≠
• Equalities or inequalities that include multiple relational operators 1 ≦ 1
< 1 + 1, 3 < π < 4, 2
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.
