Interesting note: as late as the 18th century, many mathematicians considered negative numbers to be "nonsense". Negative numbers did not become universally accepted as existing until about the same time that imaginary numbers did. Before the wide-spread acceptance of negative numbers, payments were credits and deposits were debits. A credit subtracted the payment from your balance, while a debit added the payment to your balance. After the advent of negative numbers, it was shown that subtraction is simply adding a negative number. So a payment (which is a subtraction) can be reinterpreted to be a negative number being added to your balance.
10 to the negative 18th power is equal to 1 divided by 10 to the 18th power. In other words, it is equal to 0.000000000000000001, or 1 divided by 1 followed by 18 zeros. This number is a very small decimal fraction, indicating a minute value.
The prefix that means one quintillionth, or times ten to the negative 18th power, is atto-. Examples: An attometer is a quintillionth of a meter, and an attosecond is a quintillionth of a second.

Usually its the number of the soldiers regiment. Mostly northern troops did this. Almost all the soldiers on both sides were volunteers who served in regiments raised by the states. So there was an 18th New York, and an 18th Pennsylvania, and an 18th Maine, for instance.
How to answer with formula
10 to the 18th power is called Quintrillion
10 to the 18th power is equal to 10,000,000,000,000,000,000. This is because when you raise 10 to the 18th power, you are multiplying 10 by itself 18 times. Each time you multiply, you add a zero to the end of the number, resulting in a total of 18 zeros at the end.
To read 10 to the power of 18, you would say "10 raised to the power of 18" or "10 to the 18th power." This means multiplying 10 by itself 18 times, resulting in the number 1 followed by 18 zeros, or 1,000,000,000,000,000,000.
If you're talking very late 18th century, the answer would be Napoleon Bonaparte. The rest of the 18th century was not a period of major balance of power-shifts.
