This has already been [addressed](https://support.office.com/en-us/article/Display-or-hide-zero-values-3ec7a433-46b8-4516-8085-a00e9e476b03) in Excel but I was wondering how to do the same in Google Sheets.

So suppose the B cell has this formula:

```
="frontend (days)
total: "&sum(B2,B10,B14,B20)

```

and the C cell has a similar formula. I would like the D cell to add the numbers in those two cells.
