Here are the solutions to the subtraction problems: Problem 1: r 538 \\ 189 \\ Step 1: Subtract the ones column. We cannot subtract 9 from 8, so we borrow from the tens place. The 3 in the tens place becomes 2. The 8 in the ones place becomes 18. 18 - 9 = 9 Step 2: Subtract the tens column. We cannot subtract 8 from 2, so we borrow from the hundreds place. The 5 in the hundreds place becomes 4. The 2 in the tens place becomes 12. 12 - 8 = 4 Step 3: Subtract the hundreds column. The 5 in the hundreds place became 4. 4 - 1 = 3 The result is: r 538 \\ 189 \\ 349 Problem 2: r 662 \\ 487 \\ Step 1: Subtract the ones column. We cannot subtract 7 from 2, so we borrow from the tens place. The 6 in the tens place becomes 5. The 2 in the ones place becomes 12. 12 - 7 = 5 Step 2: Subtract the tens column. We cannot subtract 8 from 5, so we borrow from the hundreds place. The 6 in the hundreds place becomes 5. The 5 in the tens place becomes 15. 15 - 8 = 7 Step 3: Subtract the hundreds column. The 6 in the hundreds place became 5. 5 - 4 = 1 The result is: r 662 \\ 487 \\ 175 3 done, 2 left today. You're making progress.
