The index of the 10 multiplier: positive to the right, negative to the left.
Examples:
- 1.234 x 105 - the index of the 10 multiplier is 5, so move decimal point 5 places to the right: 123400
- 1.234 x 10-5 - the index of the 10 multiplier is -5, so move the decimal point 5 places to the left: 0.00001234

What tells you how many places to move the decimal point in scientific notation?
Exponent
The in scientific notation tells you how many places to move the decimal?
The exponent of 10 tells you how many places to move the decimal point to the left if it is minus or to the right if it is plus.
What scientific notation tells you how many places to move the decimal point?
All scientific notation does. For example, if you have 600,000, then scientific notation would read 6*10^5, and the 5 tells you to move the decimal point to the left five numbers. And if you have 0.00006 it would read 6*10^-5, and the -5 tells you to move the decimal point to the right five numbers.
What is 1.01784001464844E-02?
The number is written in scientific notation. The -02 at the end tells you to move the decimal point two places to the left. That gives the following value:0.0101784001464844
Are numbers expressed in scientific notation using exponents?
Yes, but only to the power of 10. Scientific notation Ex: 4.6 x 10^6 (NOTE: ^ = exponent) The number in the 4.6 position has to be equal to or greater than 1 and less than 10. The number in the 10 position always has to be a 10. The number in the ^6 position tells how many places to move the decimal. If the exponent is positive the decimal moves to the right when you simplify into standard notation. If it is negative the decimal moves to the left when simplified into standard notation.
