Why does the partial sum algorithm work. As the name suggests the partial sums method calculates partial sums working one place value column at a time and then adds all the partial sums to find a total. The simple answer is that a partial sum is actually just the sum of part of a sequence.

Y 0 x 0 y 1 x 0 x 1 y 2 x 0 x 1 x 2 y 3 x 0 x 1 x 2 x 3 y 4 x 0 x 1 x 2 x 3 x 4. The nth partial sum of a sequence is usually called S n. Sigma Partial Sums are often written using Σ to mean add them all up.

A Partial Sum is the sum of part of the sequence. With the PLSO you get. Partial sum definition one of a series of sums of elements of a given sequence the first sum being the first element the second sum being the first element added to the second element the third sum being equal to the sum of the first three elements and so on.
