Here are the calculations for the number of years:

1) From 18 BC to 21 AD

Identify the type of dates.
One is BC and one is AD.
Add the years and subtract 1 (since there is no year 0).
$\text{Number of years} = 18 + 21 - 1$ $\text{Number of years} = 39 - 1$ $\text{Number of years} = 38$
The number of years is $\boxed{\text{38 years}}$ .

2) From 107 BC to 14 AD
Identify the type of dates.
One is BC and one is AD.
Add the years and subtract 1.
$\text{Number of years} = 107 + 14 - 1$ $\text{Number of years} = 121 - 1$ $\text{Number of years} = 120$
The number of years is $\boxed{\text{120 years}}$ .

3) From 200 AD to 1993 AD
Identify the type of dates.
Both are AD.
Subtract the earlier year from the later year.
$\text{Number of years} = 1993 - 200$ $\text{Number of years} = 1793$
The number of years is $\boxed{\text{1793 years}}$ .

4) From 1807 BC to 1798 BC
Identify the type of dates.
Both are BC.
Subtract the later year (smaller number) from the earlier year (larger number).
$\text{Number of years} = 1807 - 1798$ $\text{Number of years} = 9$
The number of years is $\boxed{\text{9 years}}$ .

5) From 1994 AD to 2008 AD
Identify the type of dates.
Both are AD.
Subtract the earlier year from the later year.
$\text{Number of years} = 2008 - 1994$ $\text{Number of years} = 14$
The number of years is $\boxed{\text{14 years}}$ .

Calculate the number of years between the following dates: a) 18 BC to 21 AD, b) 107 BC to 14 AD, c) 200 AD to 1993 AD, d) 1807 BC to 1798 BC, e) 1994 AD to 2008 AD
