How do you check that 376 + 128 = 504?

Subtract one addend from the sum: 504 − 128 = 376, and 504 − 376 = 128. Getting the other addend back means the sum is right.

2 carries: every time a column added up to 10 or more, its ones digit was written and 1 was carried to the next column on the left.

Is 128 + 376 the same as 376 + 128?

Yes. Addition is commutative, so both give 504; the column looks the same with either number on top.
