For instance, to enter a matrix just have the spreadsheet view open, enter the numbers, highlight the cells, then choose the option &quot;Create Matrix&quot;. To enter a vector start writing &quot;vec&quot; in the input bar at the bottom and intellisense gives you the option to choose &quot;Vector[&lt;Start Point&gt;, &lt;End Point&gt;]&quot;. Choose this. Fill it in, for example, &quot;Vector[(-3, 4), (1, 2)]&quot; (Hint: Use Tab to move between options in the input formula, here to move between &quot;&lt;Start Point&gt;&quot; and &quot;&lt;End Point&gt;]&quot;.)  Voila the vector is drawn!  You can even draw a vector with just two clicks in Graphics view, if you first select the &quot;Vectors&quot; tab at the top (the symbol is a line with an arrowhead). The GeoGebra software is really incredible for learning&#x2F;doing Linear Algebra, Calculus and Statistics. A real godsend.
