Why is my TI-36X Solar displaying the message "Error" and how can I correct it?

When "Error" appears on the display, the calculator will not accept a keyboard entry. Press the [CE/C] to clear the error condition. Press the [CE/C] twice to clear the condition and all pending operations.

• A number is divided by zero.
• The result is larger than 9.999999999 * 10^99.
• More than 15 open parentheses are used.
• More than 4 pending operations are entered.
