$\\var{q1}$ = [[0]]$\\times 10$ ^{[[1]]}

A number is in scientific notation if it is written as a decimal multiplied by some power of 10, where the decimal has exactly one digit in front of the decimal place. For example:

\n\\[1.234\\times 10^6, \\quad \\text{and} \\quad 3.01\\times 10^{-3}\\]

\nare both in scientific notation.

\n\n

Suppose we have the number $0.00023$. In scientific notation, this number would start with $2.3$ since we only want one digit in front of the decimal point. So the decimal point was here $0.00023$ and needs to move to between the $2$ and the $3$ here $2.3$. Count the places that the decimal point must jump between and you get $4$ places. That is,

\n\n\\[0.00023=2.3\\times 10^{-4}\\]

\n\nWe have a *negative four* as the power because we need to make the number $2.3$ *smaller* to get to $0.00023$
