  1. Years and Dating Boring, but necessary!

  2. Roman Numerals –counting with letters • I = 1 • V= 5 • X= 10 • L=50 • C=100 • D=500 • M=1000 • If a numeral of lesser value is in front of a numeral of greater value, subtract the lesser from the greater. • Ex: IX = 9, XL = 40, MCM = 1900

  3. Alphabet Soup – BC, AD, BCE, CE • BC and AD were created in 525 as a way to count years in relation to the birth of Christ. • BC stands for Before Christ and counts backwards from O. • AD is “Anno Domini” (In the year of our Lord) and counts forwards from O. • Why might some people not like this system?

  4. More of the Soup • BCE stands for Before Common Era and follows the same rules as BC. • CE stands for Common Era and follows the same rules as AD. • Why might this be better for academics to use this way?
