What else is on the test?

The most awaited test of the year for millions of students National Junior High School Examination (Enem) The year 2024 will happen in a few days November 3 and 10. NOT on the second day of the exam, one of the tests used will be the so-called Mathematics and its technologieswhich will occur 45 objective questions.

And Enem's math test prioritizes logical reasoning, problem-solving strategies and tries to bring this discipline closer to people's everyday lives.

“When asking a question about a specific math topic, there is a good chance that the exam will contain the information necessary to solve it in the question itself,” explains Leonardo Cavalcante, math teacher at UpMat Educacional.

Although questions may cover several topics, some are asked more frequently. See below the teacher-listed subjects that appear most often on the Enem math test and prepare for the exam!

What else do you need in mathematics at Enem?

Reading a chart

Graphs can include bar charts, pie charts, and Cartesian charts. They represent a variety of phenomena, such as the percentage of the population using a specific mode of transportation to commute to work, vehicle speed over a specific time period, the average temperature of the Earth over the years, and the relationship between two (or more) quantities in general.

Enem expects students to be able to read and remember the main information in these graphs, conduct critical analysis taking into account the socio-cultural and socio-economic contexts in which the candidate finds himself, and draw conclusions based on the evolution of the behavior of the quantities appearing in the graph .

Features

In Enem, questions often arise about the functions of the first degree (one variable) and the second degree (two variables). Functions express various relationships between sets. However, in addition to the concepts involved in studying functions, students must be able to find the results and values ​​that result from using functions. Example: a company's annual revenue calculated based on the monthly payments received plus interest on each installment.

It is common for students to create a function of one or two variables that mathematically represents a random phenomenon. Please note that a function can be represented visually as a graph on the Cartesian plane.

Percent

Another recurring theme in Enem is percentage. Every day, the population deals with payments (with interest or discounts on that payment), energy consumption (comparing whether it has increased or decreased compared to the previous month), and the division of the harvest into smaller parts (e.g. the percentage of the population moving from home to work).

Therefore, it is important that students calculate and be able to recognize the fraction (i.e. percentage) of the whole that a given value or quantity represents.

Ratio and proportion

Ratios and proportions are included in everyday mathematics in their pure form. While the concept of proportion is related to the concept of division, the concept of proportion is related to the concept of equality. Students, recognizing two or more quantities in a random situation, must be able to analyze their behavior together: if one increases when the other increases (in this case they are directly proportional) or if one decreases when the other increases (in this case in a given case they are they are inversely proportional).

Area and perimeter

Geometry appears strongly in Enem. Within this very important pillar of mathematics are the concepts of area and perimeter. Instead of using formulas, candidates must find ways to decompose a flat figure into other known ones whose areas and perimeters are easier to find, or look for similarities between these figures, resulting in numerical values ​​for their areas or perimeters.

And these calculations are directly related to reality: you can calculate the area covered by a park in a large city or the distance we will cover when we walk, for example, a few blocks.
