7101 Here the positive exponents cause the decimal place to be shifted to the right when changing from scientific notation to decimal notation. The negative exponents cause the decimal place to be shifted to the left. The 0 exponent causes no change in the decimal point. Computers use a similar notation for storage of numbers. This exponential notation differs from scientific notation in that there is no nonzero digit to the left of the decimal point. Next we will see some numbers in both scientific and exponential notation using the E notation.
