Examples:
• To enter 3.2 × 10* in calculator, enter: 3.2 EE 4 (or 3.2 EXP 4)
To enter 7.6 x 10-15, enter 7.6 EE +/- 15
• To enter 10-12, enter: 1 EE +/- 12
For (3.2 x 10* )(7.6 × 10-1> ), enter: 3.2 EE 4 × 7.6 EE +/- 15 =
The answer is 2.4 x10-10
Regardless of how your calculator writes your answer, you need to write
your answer as "x 10", not EE nor the exponent as a power on the number.
