CBSE Class 4 Maths Subtract the following Set 02

Assignment - 10

Subtract the following.

Question 1) 4705 - 2648
Answer: Arrange the numbers in columns and subtract column by column from right to left with borrowing:
Step 1: Ones column: \(5 - 8\). Borrow 1 from tens column. The 0 becomes 9 and 5 becomes 15. \(15 - 8 = 7\).
Step 2: Tens column: \(9 - 4 = 5\).
Step 3: Hundreds column: The 7 became 6 after borrowing. \(6 - 6 = 0\).
Step 4: Thousands column: \(4 - 2 = 2\).
Final Result = 2057
In simple words: Subtract the smaller number from the larger number column by column, borrowing when the top digit is smaller than the bottom digit.

Exam Tip: Always double-check your borrowing steps to avoid calculation errors.

Question 2) 7273 - 1591
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(3 - 1 = 2\).
Step 2: Tens column: \(7 - 9\). Borrow 1 from hundreds column (2 becomes 1, 7 becomes 17). \(17 - 9 = 8\).
Step 3: Hundreds column: The 1 becomes 11 after borrowing from thousands (7 becomes 6, 1 becomes 11). \(11 - 5 = 6\).
Step 4: Thousands column: \(6 - 1 = 5\).
Final Result = 5682
In simple words: Subtract each column carefully, borrowing from the next higher place value when needed.

Exam Tip: Write the numbers neatly aligned by their place values to prevent alignment mistakes.

Question 3) 5079 - 3418
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(9 - 8 = 1\).
Step 2: Tens column: \(7 - 1 = 6\).
Step 3: Hundreds column: \(0 - 4\). Borrow from thousands column (5 becomes 4, 0 becomes 10). \(10 - 4 = 6\).
Step 4: Thousands column: \(4 - 3 = 1\).
Final Result = 1661
In simple words: When subtracting from zero, borrow from the nearest non-zero digit to the left.

Exam Tip: Be extra careful when borrowing across a zero in the hundreds or tens place.

Question 4) 7123 - 2641
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(3 - 1 = 2\).
Step 2: Tens column: \(2 - 4\). Borrow 1 from hundreds column (1 becomes 0, 2 becomes 12). \(12 - 4 = 8\).
Step 3: Hundreds column: \(0 - 6\). Borrow 1 from thousands column (7 becomes 6, 0 becomes 10). \(10 - 6 = 4\).
Step 4: Thousands column: \(6 - 2 = 4\).
Final Result = 4482
In simple words: Proceed from right to left, borrowing whenever the top digit is smaller than the bottom digit.

Exam Tip: Verify your answer by adding the result (4482) to the subtrahend (2641); it should equal the minuend (7123).

Question 5) 8219 - 578
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(9 - 8 = 1\).
Step 2: Tens column: \(1 - 7\). Borrow 1 from hundreds column (2 becomes 1, 1 becomes 11). \(11 - 7 = 4\).
Step 3: Hundreds column: \(1 - 5\). Borrow 1 from thousands column (8 becomes 7, 1 becomes 11). \(11 - 5 = 6\).
Step 4: Thousands column: \(7 - 0 = 7\).
Final Result = 7641
In simple words: Line up numbers properly by their rightmost digits (ones place) when one number has fewer digits than the other.

Exam Tip: Align numbers from the right so that hundreds, tens, and ones match correctly.

Question 6) 5012 - 2764
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(2 - 4\). Borrow 1 from tens column (1 becomes 0, 2 becomes 12). \(12 - 4 = 8\).
Step 2: Tens column: \(0 - 6\). We need to borrow, but the hundreds place is 0. Borrow from thousands place first (5 becomes 4, hundreds 0 becomes 10, then borrow 1 from hundreds so hundreds become 9 and tens become 10). \(10 - 6 = 4\).
Step 3: Hundreds column: \(9 - 7 = 2\).
Step 4: Thousands column: \(4 - 2 = 2\).
Final Result = 2248
In simple words: When borrowing across zeros, change the zero to 9 as you pass through it from higher place values.

Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(5 - 2 = 3\).
Step 2: Tens column: \(0 - 2\). Borrow 1 from hundreds column (9 becomes 8, 0 becomes 10). \(10 - 2 = 8\).
Step 3: Hundreds column: \(8 - 5 = 3\).
Step 4: Thousands column: \(6 - 3 = 3\).
Final Result = 3383
In simple words: Subtract each digit column by column from right to left with necessary borrowing.

Exam Tip: Keep your working clean and legible to avoid reading errors.

Step 2: Tens column: \(3 - 6\). Borrow 1 from hundreds column (5 becomes 4, 3 becomes 13). \(13 - 6 = 7\).
Step 3: Hundreds column: \(4 - 7\). Borrow 1 from thousands column (8 becomes 7, 4 becomes 14). \(14 - 7 = 7\).
Step 4: Thousands column: \(7 - 4 = 3\).
Final Result = 3777
In simple words: Subtract normally, borrowing from the left column whenever the top digit is smaller.

Exam Tip: Double-check sequential borrows to ensure accuracy.

Question 9) 9013 - 5638
Answer: Arrange the numbers in columns and subtract column by column from right to left:
Step 1: Ones column: \(3 - 8\). Borrow 1 from tens column (1 becomes 0, 3 becomes 13). \(13 - 8 = 5\).
Step 2: Tens column: \(0 - 3\). Borrow from hundreds place (which is 0, so borrow from thousands place: 9 becomes 8, hundreds becomes 10, then borrow 1 from hundreds to make tens 10 and hundreds 9). \(10 - 3 = 7\).
Step 3: Hundreds column: \(9 - 6 = 3\).
