Section H: Subtraction Just like addition, the first step is to make the exponents the same. Instead of adding the main numbers, they are subtracted. Try to convert so that you will not get a negative answer Model: (3 x 10)-(2x 10)(30x 10)-12x10 - 28 x 10' (same exponent) = 2.8 x 101 final answer) same exponent final answer 37) (2 x 10)-(4 x10) 2 y10 38) (3 x 10)-(5 x 10- 39) (9 x 10)-(8.1 x 10) 40) (2.2 x 10)-(3 x 10)-
