Solution: Observe the example then mentally calculate subtraction of round thousands.

Answers:

7 thousand - 3 thousand = 4 thousand
So 7,000 - 3,000 = 4,000

10 thousand - 8 thousand = 2 thousand
So 10,000 - 8,000 = 2,000.

72 thousand - 42 thousand = 30 thousand
So 72,000 - 42,000 = 30,000

100 thousand - 35 thousand = 65 thousand
