Entering Digits
The digit keys enter numbers into the display. In standard notation, you can enter up to 13 digits and a decimal point. In scientific notation, you can enter 13 digits, a decimal point, and two exponent digits.Entering the Decimal Point
The [ . ] key enters a decimal point. Only one decimal point can be entered. The exponent of scientific notation cannot include a decimal point.Changing the Sign
The [ +/- ] key changes the sign of the number in the display. This enables you to enter negative numbers and negative exponents.

The [ <- ] key enables you to backspace the number in the display to replace a digit. After you replace the digit, you can continue entering data.Entering Scientific Notation
The [ EE ] key enables you to enter numbers in scientific notation. You can enter numbers as small as ±1 × 10⁻⁹⁹ or as large as ±9.999999999999 × 10⁹⁹.NOTE: If the result of a calculation is outside the range -9999999999 to -.000000001, zero, or .000000001 to 9999999999, the calculator displays the number in scientific notation even though you have not pressed [ EE ].
