from right to left, numbers are identified by:
ones, tens, hundreds, thousands, ten-thousands, hundred-thousands, millions, ten-millions ... and so on.
a quicker way is to remember that a thousand has 3 places after it. 1,000.
a million has 6 places: 1,000,000. A billion has 9: 1,000,000
So, 163.7 million dollars means you have 163 followed by 6 places AND the first place after the comma, would be a 7
$163,700,000

It wasn't until the work of Euler in the 1700's that a usefulness for imaginary numbers was found, though. See the Wikipedia articles I linked for some good information on imaginary and complex numbers. I also linked an explanatory video that is pretty good as well.
