Answer:
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.
