On the last two numbers, which aren't in standard scientific notation, you adjust the first part of the number by moving decimal places, then adjust the exponent in the other direction.

120 goes to 1.20 by moving the decimal two places to make the number smaller.

Therefore, you must make the exponent two decimal places larger,

10-6 goes to 10-4 (10-4 is larger than 10-6)

or 1.20 X 10-4 = 0.000120
