When adding cells you must use a "+" symbol, you cannot use a ":" symbol.

☐ True

☐ False

False

Explanation:

We can use both. If the total number of cells are less we can use + and add like = Sum (A1 + A2 + A3) and if cells are in sequence, and in good number then we can use ":" like = Sum (A1:A7).

With + we can only add two cells at a time, and we need to use it again and again to add all cells, like:

If we want to add in between C1 to H1, then with plus we need to write = SUM (C1+D1+E1+F1+G1+H1).

However with : we only need to write = SUM (C1:H1), and that's it.
