how to sum from multiple tables on one table?

I have 12 tables covering 4 separate pages in Numbers, with each of the 12 tables summing each row at the bottom of each table. I'd like to take the sums of each of the 12 tables, and sum each of those sums together into one table. For instance, each table is for a different location, but they each have an "attendance" box. I've summed the attendance for that location for the year, but now I'd like to set a formula so that I can sum ALL ATTENDANCE for ALL LOCATIONS.

Is there anyway to do that?

Hi jaysherrer2,
Take the formulea inclose it in parentheses as in =(B2+Table 2 :: B2+Table 3 :: B2) then divide that by the number of cells in you have in that formula.
In this example there are three =(B2+Table 2 :: B2+Table 3 :: B2)/3.

Or
Use the Average function: =AVERAGE(B2,Table 2 :: B2,Table 3 :: B2)

This will provide you an average not a total.

Hope this helps you.

Sincerely,

You can easily combine the two functions. You bracket the ROUND "around" the AVERAGE.

Take your two formulas in their basic forms.

=AVERAGE(D1:D4) will average cells D1 to D4

=ROUND(A,2) will round up number A to 2 decimal places.

Now, we want to round up the result of the Average formula so, replace the A in the ROUND with the entire AVERAGE formula above (cut and paste is good here):

=ROUND(AVERAGE(D1:D4),2)

This will first calculate your average and then round it up to 2 decimals.
If you want to round to the nearest whole number use 0

Hope this is what you need.

Hi Moich,
Good formula technique.

Another thing one could do:
This can be applied to any cell when one wants to view all, some, or none of the decimal points.
1. Click the cell with the results. (important)
2. Open Inspector
3. At the top click icon with the 42 in it.
4. Choose Decimals, change setting as desired.

It is important to first click the cell that contains the results otherwise one won't see in Inspector the decimal choice.

Hope this helps as well.
