Question about addition function

Occasional Visitor



I have a question than i cannot solve. In mi old version about mac excel, 2011, when i write "+" and click in a cell, i could click in more cells whitout write "+" and all were selected. In my new office, when i need to add a lot of numbers, i must write "+" select the cell, and repeat "+" and the next cell. 2011 version are more quickly because with one "+" i can select a lot of cells only click in its and all will be added.
