Beyond the Answer

\( 0.0021 = 2.1 \times 10^{-3} \) To convert a number into scientific notation, you move the decimal point to the right until you have a number between 1 and 10, then multiply by 10 raised to the number of places you moved the decimal. In this case, you moved the decimal 3 places to the right!
