Explanation

Subtracting 30 - 17: Since 0 < 7, borrow 1 ten from 3 tens. Now we have 10 ones and 2 tens. Subtract ones: 10 - 7 = 3. Subtract tens: 2 - 1 = 1. The answer should be 13, not 27.

Solution Steps

  1. Step 1: Write 30 - 17 in column format

  2. Step 2: Since 0 < 7, borrow 1 ten from 3

  3. Step 3: Now we have 10 ones and 2 tens

  4. Step 4: Subtract ones: 10 - 7 = 3

  5. Step 5: Subtract tens: 2 - 1 = 1

  6. Step 6: Correct answer = 13, not 27
