Column Addition
Column addition is the primary method of summing multi-digit numbers together by aligning digits into corresponding ones, tens, hundreds, etc., and carrying over sums greater than 9 to the left adjacent column:
$$x_1 + x_2 + x_3 + \dots + x_n = \sum_{i=1}^{n} x_i$$
Our visualizer lines up the digits automatically for easier understanding.
