2. Count from the leftmost digit in the random number table, which is the first row. For example: 5 rows and 2 columns, and then count to the fifth row.

3. After determining the target line, count down, and the top column is the first column. For example: 5 rows and 2 columns, and then count to the second column on the basis of the fifth row.

4. The number in the obtained location is the number you need to find.

High school math skills

1, matching method

The most commonly used matching method is completely flat method, which is an important constant deformation method in mathematics. It is widely used in factorization, simplifying roots, solving equations, proving equality and inequality, finding extreme values of functions and analytical expressions.

2, factorization method

There are many methods of factorization, such as extracting common factors, formulas, grouping decomposition, cross multiplication and so on. Middle school textbooks also introduce the use of decomposition and addition, root decomposition, exchange elements, undetermined coefficients and so on.
