    next, after you get 37.8 x 10^-1 you have to adjust the decimal point you want 3.78 (move the point to the left) when you make the 37.8 --> 3.78 you make it 10 times smaller. to compensate you make the 10^-1 ten times bigger (add 1 to the exponent) 3.78 x 10^0

    ohh yeah so do you always subtract 1 to the exponent

    we changed the exponent from -1 to 0 (we added 1, not subtracted)

    what you do to the exponent depends on the number if you got 0.378 x 10^-1 you want 3.78 so you make 0.378 bigger by multiplying by 10 to compensate, you make the 10^-1 smaller by dividing by 10 (subtract 1 from the exponent) you would get 3.78 x 10^-2

    so you can't have a number less than 1 or greater than 10
