Here are the calculations for the number of years: 1) From 18 BC to 21 AD Step 1: Identify the type of dates. One is BC and one is AD. Step 2: Add the years and subtract 1 (since there is no year 0). Number of years = 18 + 21 - 1 Number of years = 39 - 1 Number of years = 38 The number of years is 38 years. 2) From 107 BC to 14 AD Step 1: Identify the type of dates. One is BC and one is AD. Step 2: Add the years and subtract 1. Number of years = 107 + 14 - 1 Number of years = 121 - 1 Number of years = 120 The number of years is 120 years. 3) From 200 AD to 1993 AD Step 1: Identify the type of dates. Both are AD. Step 2: Subtract the earlier year from the later year. Number of years = 1993 - 200 Number of years = 1793 The number of years is 1793 years. 4) From 1807 BC to 1798 BC Step 1: Identify the type of dates. Both are BC. Step 2: Subtract the later year (smaller number) from the earlier year (larger number). Number of years = 1807 - 1798 Number of years = 9 The number of years is 9 years. 5) From 1994 AD to 2008 AD Step 1: Identify the type of dates. Both are AD. Step 2: Subtract the earlier year from the later year. Number of years = 2008 - 1994 Number of years = 14 The number of years is 14 years.
