Chapter 1 - Whole Numbers - 1.3 Subtracting Whole Numbers - 1.3 Exercises - Page 28: 41



Work Step by Step

The 1 in the ones place is less than 2, so in order to subtract we first have to regroup from the tens digit to turn 1 to 11. Then we subtract 11-2 = 9 for the ones column. Then we subtract 6-5 = 1 for the tens column. Finally we subtract 7-2 = 5 for the hundreds column. From the 5 in the hundreds place, 1 in the tens place, and 9 in the ones place, we get 519.
