Look at this table, which shows the place value of numbers up to millions.
You should know the value of each column and understand how each number is written.
*Notice the table says units. Units are another word for ones.
In 6025 the 6 is in the Thousands column, so is worth 6000.
In 6 092 047 the 6 is in the Millions column, so is worth a massive 6 000 000.
In 1 234 567 the 6 is only in the Tens column, so is worth only 60.
