Albert's mistake can be attributed to improperly handling the addition of the digits in the correct place values, leading to an incorrect sum. The specific issue is:
**Albert forgot to carry a ten over to the next column of digits.**
Here's how the addition should look:
```
346
+ 51
-----
397
```
When adding the "4" (from 346) and "5" (from 51) in the tens place, Albert should have correctly calculated that "4 + 5 = 9" and added that with 3 in the hundreds and 6 and 1 in the units place. Thus, the correct sum should be 397, not 856.
