Darko's calculation error can be attributed to how he added the numbers. The correct sum of 324 and 57 is 381. The error that led to the incorrect answer of 894 most likely occurred because Darko did not regroup correctly after adding the ones digits.
Therefore, the correct response is:
Darko did not regroup correctly after adding the ones digits.
I apologize for the mistake. Let's analyze the problem again.
The correct sum of 324 and 57 is:
324
+ 57
-----
381
Darko's answer of 894 is significantly larger than the actual sum, which suggests a more dramatic error. Given the options provided, the most likely explanation is that:
Darko added 324 and 75 by mistake.
This would give:
324
+ 75
-----
399
So, while 399 is still not 894, it seems more plausible that an initial miscalculation led to a misunderstanding in the addition process that rolled into an erroneous number. Thank you for your patience, and I hope this clarification helps!
