Albert made a mistake when adding 4 tens + 5 tens.

Answer 1

The correct response is:

Albert made a mistake when adding 4 tens + 5 tens.

When adding 346 and 51, the correct addition would involve adding the tens correctly. The tens in 346 (which is 40) and the tens in 51 (which is 50) should be added correctly to produce a result of 397, not 856.
