Partial Sums Addition Algorithm
Partial Sum Addition involvesThinking of the place value of the digits in
the numbers, Finding partial sums by adding parts of
numbers according to their place value, andAdding partial sums together to get a total
Partial Sums Addition
Solve 268 + 483
Begin by thinking of the expanded notation for the numbers being added:
268 = 200 + 60 + 8483 = 400 + 80 + 3
268+ 483
600Add the hundreds (200 + 400)
Add the tens (60 +80) 140Add the ones (8 + 3)
Add the partial sums(600 + 140 + 11)
+ 11751
785+ 6411300Add the hundreds (700 + 600)
Add the tens (80 +40) 120Add the ones (5 + 1)
Add the partial sums(1300 + 120 + 6)
