A few examples of
exponential notation
 Exponential Notation
not much here

 Rough Draft
Here are some random additional examples of exponential notation.

Whats a 1000 divided by 10?
1,000. / 10. =
103 / 101 =
103 - 1 =
102 =
100.

Whats a million times a billion? (Here is a list.)
Well, a million is 1,000,000.
So a million times a billion is 1,000,000. × 1,000,000,000. =
106 × 109 =
106 + 9 =
1015 =
Oh my, a 1. with 15 zeros, err...
1,000,000,000,000,000.

4,000,000,000 / 100 ?
(4. × 109) / (1. × 102) =
(4. / 1.) × 109) / (1. × 102) =
What is 100. × 1,000.?
(1. × 102) × (1. × 103)
Here is what makes it easier: 10a × 10b = 10 a + b !
(Dividing is similar, 10a / 10b = 10 a - b )
So... 102 × 103 = 10 2 + 3 = 105, and
100. × 1,000. =
(1. × 102) × (1. × 103) =
(1. × 1.) × 105 = 1. × 105
= 100,000.

Sorry, I've made this difficult.
Since 100. is 1. × 102, you would really just say 100 = 102.
So 100 × 1000 = 102 × 103 = 102 + 3 = 105 = 100,000.
I mixed in the 1.'s so you could do things like 600 × 4000.
(6. × 102) × (4. × 103) = (6. × 4.) × 102 + 3 = 24. × 105 = 2,400,000.
You could even divide them. Whats 600 / 4000?
(6. × 102) / (4. × 103) = (6. / 4.) × 102 - 3 = 3/2 × 10-1 =
1.5 × 10-1 = .15
(Though we usually write 0.15 to make sure noone overlooks the decimal.)

Overhaul or punt. Seems of little value as is.
