  5. Solutions: a) 1498 and 1532? Step 1: Set out the years as a subtraction equation. 1532 -1498 Step 2: Calculate. 34 Step 3: Write the answer in years. 34 years difference

  6. Solutions: b) December 1983 and December 2005? Step 1: Set out the years as a subtraction equation. 2005 -1983 Step 2: Calculate. 22 Step 3: Write the answer in years. 22 years difference

  7. Solutions: c) 12 April 1978 and 15 April 1983? (without leap years) Step 1: Find how many years are between 12 April 1978 and 15 April 1983. 1983 -1978 5 years Step 2: Calculate how many days are left over. 15 -12 3 days Step 3: Write the answer in years and days. 5 years and 3 days difference

  8. BC and AD History is divided into two eras: BC and AD BC stands for before Christ AD stands for Anno Domini, meaning in the time of our Lord and this is the beginning of the era. The AD period starts at AD 1. Each year after this time is increased by 1 (AD 1, AD 2, AD 3......). If the year is AD 2010, it means 2010 years after Christ was born. To help us describe the time before this date we use BC and count backwards. If an event occurred at a time 350 years before Christ was born then we call this time 350 BC. The is no year between 1BC and AD 1.

  9. How much time is there between AD 232 and AD 530? Step 1: As both years are AD, write as a subtraction. 530 -232 Step 2: Calculate. 298 Step 3: Write the answer in years. 298 years difference

  10. How much time is there between 232 BC and AD 530? Step 1: There are 232 years before 1. 232 Step 2: There are 530 years after year 1 +530 Step 3: Add. 762 Step 4: Write the answer in years. 762 years difference
