Greater than or equal key –– The key is used to enter a “greater
than or equal” (
w) symbol between two values in a formula, which
produces a logic “1” result if the left operand is greater than or equal to
the right operand; otherwise, it produces a logic “0” result.
•
Less than or equal key –– The key is used to enter a “less than or
equal” (
v) symbol between two values in a formula. It produces a “1”
result if the left operand is less than or equal to the right operand;
otherwise, it produces a “0” result.

Equal key –– The key is used to enter an equal (
+) symbol between
two values in a formula. It produces a “1” result if the left operand is
equal to the right operand; otherwise, it produces a “0” result.

between two values in a formula. It produces a “1” result if the left

•
Open parenthesis key –– The key is used to place an open
parenthesis () symbol at the beginning (left) of some group of values in

which is 127 characters.
•

parenthesis () symbol at the ending (right) of some group of values in
formula. It is used to close an open parenthesis.
