That's why logs are used. So let's represent this guy as well. So this guy ten to negative five is equal to one over 100,000, which is 0.1
and equivalently on the log scale if you're presented in terms of negative log of base ten of 0.0001, and that equals to five. Now notice what happens. A decrease of tenfold going from this guy to this guy increases by increment of only one, going from four to five. Now, let's represent ten to negative six and ten to negative seven as well.
