B. Equalities or inequalities involving multiple relational operator

1 ≤ 1 < 1 + 1; 3 < π < 4; 2

= 2 + 2 = 4; 2 + 2 = 4 < 6; 2 + 3

= 5 ≠ 2 + 5 = 8; etc.

• The values and expressions you can input on the display

• The expression entry is up to 99 bytes, including the left,

the right side and the relational operators.

• Pressing the

  keys displays a menu of functions.

Press the number key that corresponds to the function you

want to input.

• In the expression with no relational operator, press ,

the system will automatically join “= 0” as the end of the

or function (Example: , cos (8 • 9))

C. An expression in which relational operators are

surrounded by parentheses. (Example: 8 < (9 < 10))

D. An expression in which there are multiple relational

operators which are not oriented in the same direction

(Example: 5

≤

6 ≥ 4)

E. An expression that contains two of the following

relational operators in any combination (Example: 4 < 6 • 8)

F. An expression contains relational operators consecutive

(Example: 5 ≥ > 4)
