If the considered result is not equal to either of these two numbers, it will not be displayed. The formula is changed to = if (sum (n ({1; 3}=A 1), index ({1; 3}，MIN(IF({ 1； 3 } & lt& gtA 1，ROW( 1:2)，""))，" ").
Computational aspects of mathematics
Even occupies a dominant position in elementary mathematics. Its position in higher mathematics is also obvious. In addition to many theoretical subjects, advanced mathematics also has a large number of computational subjects, such as differential equations, computational mathematics, statistics and so on. With highly abstract theoretical equipment, it is possible for these disciplines to deal with complex computing problems in modern science and technology.
