When we subtract 1,000 from a four-digit number, we need to decrease the digit in the thousands column by 1.
Here is the number 4,705 shown on an abacus.
Notice that the abacus says units. Units are another word for ones.
When we subtract 1,000 from it, we take away one digit from the thousands column.
4,705 - 1,000 = 3,705
Example 1
Subtract 1,000 from:
5,097
Answer
We decrease the 5 in the thousands column by 1 to get 4 in that column.
5,097 - 1,000 = 4,097
Example 2
Subtract 1,000 from:
1,060
Answer
We decrease the 1 in the thousands column by 1 to get 0 in that column.
Remember to leave off any zeros on the left-hand side of a number.
1,060 - 1,000 = 0060 = 60
Does that make sense?
