1, open the required Excel file on the computer to enter.
2. After entering the Excel file, enter =COUNTIF(B2:B7, "& gt=90"). Represents the total number of people with 90 points or more.
3. Then continue to enter -COUNTIF(B2:B7, "> 100"). The two COUNTIF formulas mean that the total number of people with more than 90 points minus 100 points is more than 90 points and less than 100 points.
