What are the sums of the following sets of numbers? 501 + 463, 302 + 132, 200 + 513, 154 + 532, 357 + 321, 155 + 448, 426 + 303, 214 + 416, 848 + 53.
Understand the Problem
The question involves adding multiple sets of numbers together to find the sums for each row. Each row contains two numbers that need to be added.
Answer
The sums for each row are \( 964, 434, 713, 686, 678, 603, 729, 630, 901 \).
Answer for screen readers
The sums for each row are:
- 964
- 434
- 713
- 686
- 678
- 603
- 729
- 630
- 901
Steps to Solve
-
Add the first row: 501 and 463
Start by adding the two numbers in the first row: $$ 501 + 463 = 964 $$
-
Add the second row: 302 and 132
Add the two numbers in the second row: $$ 302 + 132 = 434 $$
-
Add the third row: 200 and 513
For the third row: $$ 200 + 513 = 713 $$
-
Add the fourth row: 154 and 532
Finally, add the numbers in the fourth row: $$ 154 + 532 = 686 $$
-
Add the fifth row: 357 and 321
Proceed with the fifth row: $$ 357 + 321 = 678 $$
-
Add the sixth row: 155 and 448
Then add the sixth row: $$ 155 + 448 = 603 $$
-
Add the seventh row: 426 and 303
Next, calculate the seventh row: $$ 426 + 303 = 729 $$
-
Add the eighth row: 214 and 416
Move on to the eighth row: $$ 214 + 416 = 630 $$
-
Add the ninth row: 848 and 53
Finally, add the last row: $$ 848 + 53 = 901 $$
The sums for each row are:
- 964
- 434
- 713
- 686
- 678
- 603
- 729
- 630
- 901
More Information
These calculations are crucial for understanding basic addition. Each row adds two numbers together, demonstrating how to handle calculations correctly.
Tips
- Skipping a row or misaligning numbers can lead to errors.
- Forgetting to carry over when the sum exceeds 10 in a column can also lead to incorrect results.
