Explanation

The chapter demonstrates addition of large numbers using place value. We add 1,855 and 1,862 by aligning digits properly: Ones: 5+2=7, Tens: 5+6=11 (write 1, carry 1), Hundreds: 8+8+1=17 (write 7, carry 1), Thousands: 1+1+1=3. Total: 3,717 km.

Solution Steps

  1. Step 1: Set up addition: 1,855 + 1,862

  2. Step 2: Add ones: 5 + 2 = 7

  3. Step 3: Add tens: 5 + 6 = 11, write 1, carry 1

  4. Step 4: Add hundreds: 8 + 8 + 1 = 17, write 7, carry 1

  5. Step 5: Add thousands: 1 + 1 + 1 = 3

  6. Step 6: Total: 3,717 km
