CBSE Class 4 Maths Addition Worksheet Set 05

A. FILL IN BLANKS:

Question 1. The sum of two or more numbers is called ___________ and the numbers which are added are called ___________.
Answer: sum, addends
In simple words: The result of addition is called the sum, and the numbers being added are the addends.

Exam Tip: Memorize these fundamental vocabulary terms as they frequently appear in conceptual fill-in-the-blank questions.

Question 2. The numbers added in any order gives the ___________ same.
Answer: sum
In simple words: Changing the order of addends does not change the total (Commutative Property of Addition).

Exam Tip: This illustrates the commutative property: \(a + b = b + a\).

Question 3. When zero is added to any number the sum is the ___________.
Answer: number itself
In simple words: Adding 0 to any number leaves the number unchanged (Additive Identity Property).

Exam Tip: Zero is known as the additive identity element.

Question 4. We add ___________ to a number to get its successor.
Answer: 1
In simple words: The successor of any number is found by adding 1 to it.

Exam Tip: Always remember that successor means next number (\(\text{Number} + 1\)).

Question 5. The sum of the place value and face value of 4 in the number 74,23,608 is ___________.
Answer: 4,00,004
Place value of 4 in 74,23,608 = 4,00,000
Face value of 4 = 4
Sum = 4,00,000 + 4 = 4,00,004

Exam Tip: Face value is the digit itself, whereas place value depends on the position of the digit in the number.

Question 6. The sum of the largest 7 digit number and 1 is ___________.
Answer: 1,00,00,000 (1 crore)
Largest 7-digit number = 99,99,999
Sum = 99,99,999 + 1 = 1,00,00,000

Exam Tip: Adding 1 to the greatest \(n\)-digit number always gives the smallest \((n+1)\)-digit number.

Question 7. The number which is 600 more than 695482 is ___________.
Answer: 6,96,082
Calculation:
\(695482 + 600 = 696082\)

Exam Tip: The word "more than" indicates addition.

Question 8. The sum of the largest and the smallest numbers formed by using all the digits 3, 8, 5, 0, 4 and 6 is ___________.
Answer: 11,59,287
Given digits: 3, 8, 5, 0, 4, 6 (6 digits)
Largest 6-digit number formed = 865430
Smallest 6-digit number formed = 304568 (Note: cannot start with 0)
Sum = 865430 + 304568 = 1159287

Exam Tip: When forming the smallest number, never place 0 at the extreme left (highest place value position).

B. FILL IN THE MISSING NUMBERS:

Question 1. 52648 + 7389 = ___________ + 52648
Answer: 7389
In simple words: Order of addition does not matter.

Exam Tip: Apply the commutative property of addition (\(A + B = B + A\)).

Question 2. 12504 + ___________ + 28765 + 74095 = 28765 + 74095 + ___________
Answer: 12504, 12504
In simple words: Both sides of the equation must have the exact same set of numbers.

Exam Tip: Compare the addends on both sides to find the missing numbers.

Question 3. 9999 + 52498 + 1 = ___________
Answer: 62498
Calculation:
\(9999 + 1 = 10000\)
\(10000 + 52498 = 62498\)

Question 4. ___________ + 1 = 500000
Answer: 499999
Calculation:
\(500000 - 1 = 499999\)

Exam Tip: This is finding the predecessor of 5,00,000.

Question 5. 9876543 + ___________ = 9876543
Answer: 0
In simple words: Adding zero leaves the number unchanged.

Exam Tip: Remember the identity property of addition.

Question 6. 953700 + ___________ = 954000
Answer: 300
Calculation:
\(954000 - 953700 = 300\)

Exam Tip: Find the difference between the target sum and the given addend.

Question 7. 9999999 + 1 = ___________
Answer: 10000000 (1 crore)
In simple words: Adding 1 to the largest 7-digit number gives the smallest 8-digit number.

Exam Tip: Count the zeros carefully when writing large numbers.

Question 8. 546787 + 2113 = ___________
Answer: 548900
Calculation:
\(546787 + 2113 = 548900\)

Exam Tip: Align digits properly by their place values before adding vertically.

C. ARRANGE THE FOLLOWING NUMBERS IN COLUMNS AND FIND THEIR SUM:

Question 1. 315698 + 252481 + 3078
Answer: 5,71,257
Arranging in columns:
  3,15,698
+ 2,52,481
+     3,078
----------------
  5,71,257
In simple words: Align the numbers by place value and add column by column from right to left.

Exam Tip: Ensure proper column alignment, especially for numbers with fewer digits like 3078.

Question 2. 38567 + 185679 + 79843
Answer: 3,04,089
Arranging in columns:
    38,567
+ 1,85,679
+   79,843
----------------
  3,04,089
In simple words: Add each column carefully, carrying over values to the next left column when the sum is 10 or more.

Exam Tip: Double-check carry-over digits to avoid arithmetic errors.

D. WHICH NUMBER IS :

Question (a) 89 more than 345611 ?
Answer: 345,700
Calculation:
\(345611 + 89 = 345700\)

Exam Tip: "More than" means you need to perform addition.

Question (b) 437 more than 266453 ?
Answer: 266,890
Calculation:
\(266453 + 437 = 266890\)

Question 1. In Noida schools the number of children who appeared for Olympiad Exam in year 2007 were 25,186 and in year 2008 were 27,619. How many children appeared in both the years together?
Answer: 52,805 children
Number of children in 2007 = 25,186
Number of children in 2008 = 27,619
Total children in both years together = 25,186 + 27,619 = 52,805
In simple words: To find the combined total for both years, add the two numbers.

Exam Tip: Keywords like "together" or "total" indicate addition.

Question 2. The Essel world had 1,32,767 visitors in 1998. In 1999 it had 1,747 more visitors than 1998. How many people in all visited Essel world in the 2 years.
Answer: 2,67,281 visitors
Visitors in 1998 = 1,32,767
Visitors in 1999 = 1,32,767 + 1,747 = 1,34,514
Total visitors in both years = 1,32,767 + 1,34,514 = 2,67,281
In simple words: First find the number of visitors in 1999 by adding 1,747 to 1998 visitors, then add the visitors of both years.

Exam Tip: Read multi-step problems carefully; do not directly add 1,747 to the 1998 total for the final answer.

Question 3. An Indian Air Lines aeroplane flew 76,523 km in one week, 67,717 km in the second week and 7,739 km in the third week. Find the distance covered by the plane in these 3 weeks.
Answer: 1,51,979 km
Distance in 1st week = 76,523 km
Distance in 2nd week = 67,717 km
Distance in 3rd week = 7,739 km
Total distance = 76,523 + 67,717 + 7,739 = 1,51,979 km
In simple words: Add the distances of all three weeks to get the total distance covered.

Exam Tip: Include proper units (km) in your final statement.

Question 4. The number 3,95,436 is given. Interchange the digits at lakhs place and thousands place. Find the sum of the original number and the new number.
Answer: 8,90,872
Original number = 3,95,436
Digit at lakhs place = 3
Digit at thousands place = 5
New number after interchanging lakhs and thousands digits = 5,93,436
Sum of original number and new number = 3,95,436 + 5,93,436 = 8,90,872
In simple words: Swap the digit in the lakhs place with the digit in the thousands place, then add the two numbers together.
