Estimate and then find all of the values. 345,000 - 83,723

62,089 + 490,076

87,002 - 49,725

4,892 + 99

17,000 - 4,568

7,718 + 89

82,780 - 998

10,000 - 985

892 + 498

6,500 - 87

84,345 + 142

300,000-80,000 equals 220,000

60,000+500,000 = 560,000

90,000-50,000 = 40,000

5000+100 = 5100

17,000-5000 equals 12,000

8,000 +100 = 8100

10,000 - 1000 = 9000

1000+500 = 1500

7000-100 = 6900

100,000 + 100 equals 100,100
