1. How to use the help file
The help document is as follows, there are specific meanings of function parameters, and a video introduction to the usage:
1. The use of if function, if is similar to three operators,
If it is satisfied, display the first parameter, otherwise display the second parameter
If multiple tables are written in the if condition, use + to indicate or, * to indicate and
2. The first parameter of sumif is the column area of the condition, the second parameter is the specific value of the condition, and the third parameter is the column to be calculated.
3. sumifs, you can add multiple fields, which is equivalent to the operation in sql
sum (score) where class = second class and serial number>10
The first parameter is the score column that needs sum, the second parameter is the area of condition 1, the third parameter is the expression of condition 1, and the four parameters are the area of condition. . . .
4. Application type of the cell,
Apply A35 as follows
Here is a relative reference. If my cell is filled in different directions, the relative position will change.
Press F4 for the first time, it will become an absolute reference.
Press F4 for the second time, and it becomes the column feel referenced
Press F4 for the third time, it becomes an absolute line quote
