1. Personnel working in the field of electricity and electronics are frequently called upon to perform mathematical calculations in order to predict or confirm proper circuit operation. 2. The numbers involved in calculations in the field of electricity and electronics are often extremely large or extremely small. 3. The invention and widespread use of modern electronic calculators has relieved us of the need to manipulate numbers in scientific notation. 4. The term quantum notation refers to a special way of using powers of 10. 5. In order to determine the scientific notation for a number, count the number of spaces that the decimal point has to be moved in order to appear behind the first digit. This count, the number of spaces moved, becomes your exponent in the power of 10.
