Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
So, we're gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.
