The same letter in EXCEL represents different numbers in different cells, as shown in the figure. A after different people represents different numbers.

E3 = e 19/(E3+E6+E7+E8+e 1 1)* E3

If E3 is not equal to 0,

Then1= e19/(E3+E6+E7+E8+e11).

e 19 = E3+E6+E7+E8+e 1 1

E3 = e 19-E6-E7-E8-e 1 1

How to let the cells represented by column A participate in the calculation? If a is a concrete and different number, how do you know which cells in a column of numeric cells represent a? You can't do it without specifying specific functions, and don't expect the computer to tell fortune.
