All questions of Addition for Class 1 Exam

51+28=79

Break 82 and 13 into tens and ones:
82 = 80 + 2, 13 = 10 + 3
Add tens: 80 + 10 = 90
Add ones: 2 + 3 = 5
Now add the results: 90 + 5 = 95
Thus, the correct answer is Option B.

Break 58 and 19 into tens and ones:
58 = 50 + 8, 19 = 10 + 9
Add tens: 50 + 10 = 60
Add ones: 8 + 9 = 17
Now add the results: 60 + 17 = 77
Thus, the correct answer is Option C.

Understanding the Addition Problem
When faced with the problem of adding two numbers, such as 67 and 16, it’s important to break it down step by step for clarity.
Step 1: Align the Numbers
- Start by writing the numbers one under the other, aligning them by place value:

67
+ 16
Step 2: Add the Units Place
- Look at the rightmost digits (units place):
- 7 (from 67) + 6 (from 16) = 13
- Write down 3 and carry over 1 to the next column (tens place).
Step 3: Add the Tens Place
- Now, move to the left column (tens place):
- 6 (from 67) + 1 (from 16) + 1 (carried over) = 8
- So, write down 8.
Step 4: Combine the Results
- Now, combine the results from the two columns:
- The answer is 83.
Conclusion
Therefore, 67 + 16 = 83. Hence, the correct answer is option 'B'.
This methodical approach to addition not only helps in arriving at the correct answer but also reinforces the understanding of place value and carrying over in addition.

Break 62 and 37 into tens and ones:
62 = 60 + 2, 37 = 30 + 7
Add tens: 60 + 30 = 90
Add ones: 2 + 7 = 9
Now add the results: 90 + 9 = 99
Thus, the correct answer is Option D.

Understanding the Question
In the problem, we need to find the sum of two numbers: 39 and 27.
Step-by-Step Addition
To perform the addition, follow these simple steps:
- Align the Numbers: Write the numbers one under the other, aligning them by their rightmost digits.
39
+ 27
- Add the Units Place: Start by adding the digits in the units place (rightmost):
- 9 (from 39) + 7 (from 27) = 16
- Write down 6 and carry over 1 to the next column.
- Add the Tens Place: Next, add the digits in the tens place along with the carry:
- 3 (from 39) + 2 (from 27) + 1 (the carry) = 6
- Combine the Results: Now, combine both results:
- The sum of the units place is 6, and the sum of the tens place is 6.
- Therefore, the final result is 66.
Conclusion
Thus, the correct answer to the addition of 39 and 27 is 66, which corresponds to option 'C'.
By breaking down the process, we see that simple addition can be easily managed with proper alignment and carrying techniques.

Break 76 and 23 into tens and ones:
76 = 70 + 6, 23 = 20 + 3
Add tens: 70 + 20 = 90
Add ones: 6 + 3 = 9
Now add the results: 90 + 9 = 99
Thus, the correct answer is Option A.

Break 94 and 23 into tens and ones:
94 = 90 + 4, 23 = 20 + 3
Add tens: 90 + 20 = 110
Add ones: 4 + 3 = 7
Now add the results: 110 + 7 = 117
Thus, the correct answer is Option A.

Break 35 and 12 into tens and ones:
35 = 30 + 5, 12 = 10 + 2
Add tens: 30 + 10 = 40
Add ones: 5 + 2 = 7
Now add the results: 40 + 7 = 47
Thus, the correct answer is Option C.

Break 41 and 19 into tens and ones:
41 = 40 + 1, 19 = 10 + 9
Add tens: 40 + 10 = 50
Add ones: 1 + 9 = 10
Now add the results: 50 + 10 = 60
Thus, the correct answer is Option B.
