Answer: (A)

To find the sum of 436 and 79, you start by aligning the numbers by their place value: ``` 436 + 79 ------ ``` Next, you add the numbers column by column, starting from the rightmost column: 1. In the units column, add 6 and 9, which equals 15. Write down 5 and carry over 1 to the next column. 2. In the tens column, add 3 (from 436), 7 (from 79), and the 1 that you carried over. That gives you 3 + 7 + 1 = 11. Write down 1 and carry over 1. 3. Finally, in the hundreds column, add 4 (from 436) and the carried over 1, which totals 4 + 1 = 5. Placing all these together, you get: ``` 436 + 79 ------ 515 ``` Thus, the sum of 436 and 79 is correctly calculated as 515. This confirms that the right answer is accurately reflected in the choice provided.
