The shortest way to add these six cells is:

=sum(a1+a2+a3+a4+a5+a6)

☐ true
☐false

The answer to the given question is "False".

Explanation:

In the spreadsheet for add six cells, we use the formula like this that can be described as below:

Formula: =SUM(A1:A6)

To add cells in the spreadsheet we use the sum function. In the function parenthesis, we pass the range to add the number that is A1: A6. In this range, the A1 stands for the first cell and the A6 stands for the last cell. This formula adds six cells.

That's why the answer to this question is "False".
