55

2 + 200 + 55 = 257

Add up Method The add up method is similar to the standard algorithm because you can use the solution to the add up method and add it to the smaller amount in the standard algorithm. 655-398=257 which can be checked by showing 257+398=655

Partial Sums MethodPartial sums is similar to the standard addition algorithm because the place values stay the same. Instead of regrouping, you just write the partial sum below the problem.
