An algorithm is a set of rules for solving a math problem.
The Partial Sums method is a two-stage process. In the first stage one looks at each
column (working left to right) and adds up the place-values represented by the digits in that
column. In the second stage those partial sums are added together.
column (working left to right) and adds up the place-values represented by the digits in that

Step-1: Add up the
hundred place =700
Step two: add the
tens place. =140
Step-3: add up the
ones place =11
Step-4 add all the
partial sum to find
answer. =851
