Online calculator for adding two vectors with 2 elements
The following formula is calculated
\(\displaystyle\left[\matrix{x1\\y1}\right] + \left[\matrix{x2\\y2}\right] = \left[\matrix{x1+x2\\y1+y2}\right]\)
To perform the addition enter the vectors that should be added, then click the 'Calculate' button. Empty elements are counted as 0.

Vectors can be added by adding the individual elements. However, vectors can only be added if the number of dimensions and their direction (column or roworiented) are the same.
The following vectors can be added. They have the same number of elements and direction.
The vectors \(\left[\matrix{X_a\\Y_a}\right] + \left[\matrix{X_b\\Y_b}\right]\) and \(\left[\matrix{X_a\\Y_a\\Z_a}\right] + \left[\matrix{X_b\\Y_b\\Z_b}\right]\) can be added.
The following vectors cannot be added because they have different numbers of elements.
The vectors \(\left[\matrix{X_a\\Y_a}\right] + \left[\matrix{X_b\\Y_b\\Z_b}\right]\) cannot be added.
The following vectors cannot be added because they have a different orientation
The vectors \([X_a\;Y_a\;Z_a]+ \left[\matrix{X_b\\Y_b\\Z_b}\right]\) cannot be added.
Example
\(\left[\matrix{a\\b\\c}\right] + \left[\matrix{x\\y\\z}\right] = \left[\matrix{a+x\\b+y\\c+z}\right]\)
\(\left[\matrix{1\\2\\3}\right] + \left[\matrix{10\\20\\30}\right] = \left[\matrix{1+10\\2+20\\3+30}\right] =\left[\matrix{11\\22\\33}\right] \)
