    Percent is literally "Per cent" - 1/100th ratio, like cents on the dollar or pence on the pound.

    As in, a dollar increased by 8% is $1.08

    For any other value to be changed by a percentage, image you are doing it for a dollar or 1.00 then multiply or divide by that amount, as appropriate.

    20 x 1.08 = 21.6

    ... x 10^something is simply shifting the decimal point.

    -1 means shift it one place to the left:

    2.03 x 10^-1 = 0.203

    What does this have to do with finance?

    Yes, I CAN do 3rd grade math in my head.

    NO, I don't intend to do your homework.

    You actually asked if anyone CAN, not for the answer to you homework questions.
