Tiny Numbers!
Okay, a tiny number, (like the size of a cell,) is pretty much the same as large numbers in Scientific Notation, except you have to deal with negatives. "Oh, great," you are probably thinking, "MORE negatives." But, actually, this is much easier than multiplying and dividing with them. Give 'em a chance.
Back to business! First, moving your decimal place is different. You have to move it BACKWARDS to after the first digit. Fun, eh?
Lets try it.
Lets say... we have the decimal .0000000123
And... we want to write it in Scientific Notation. We need to move our decimal over.
But... Where would we put it? After the first digit.
00000001.23
Much better. Now, our number before the ten is less than ten. Perfect. Now, just remember where your decimal used to be, and where it is, and start counting those places you moved the decimal over by.
0 0 0 0 0 0 0 1.2 3
1 2 3 4 5 6 7 8

Okay, a tiny number, (like the size of a cell,)
And he is .000000000000587 of an inch big. So, how can he write his size in a smaller format for his doctor? Scientific Notation!!!
Now, lets move that rouge decimal over.
0000000000005.87
Get rid of those zeroes... and write our number...
5.87 13
Now we use our power of ten and negative exponent to put them back.
