1, parity method: In order to avoid the situation that students' correct rate is zero, experts will specially set some special options when setting options: ① The options are set to three odd numbers and an even number, and it is more likely to choose even numbers. (2) Using parity to predict and simplify the calculation process.
2. Division: According to the division relationship provided by the stem information, quickly select the answer.
3. Substitution method: directly substitute the options into the stem to verify the answer.
Review skills:
The mathematical problems in the administrative professional ability test mainly include one kind of questions: numerical reasoning.
Four kinds of operational relations should be established in digital reasoning. The types of general numerical reasoning problems are arithmetic progression, geometric progression, sum series, polynomial series and so on. The sensitivity to numbers and sequences is mainly investigated. Such as some basic properties of numbers, odd or even numbers, prime or composite numbers, integers or decimals or fractions. There are also some square series and cubic series.
It is required to master the cubic number of 1-1 and their numbers after adding and subtracting1,and the square number of 1-2 1 and their numbers after adding and subtracting1. Sequence sensitivity refers to whether it is sensitive to a group of numbers, especially to a group of numbers with local characteristics.
Digital reasoning questions mainly investigate the positional relationship or logical relationship between numbers. When we see a set of related numbers, we need to quickly establish four operational relationships. But also to establish a correct way of thinking, that is, horizontal recursion, vertical extension and network construction.
Transverse recursion mainly looks at the four operational relationships between a number and the next number or between the first two numbers and the next number. Vertical extension is to change a number into another form to find new laws. It is an idea to construct a network with difference sum quotient.
