Quantitative Reasoning Math: Everything You Need to Know

Quantitative Reasoning Math

It will not be too farfetched to claim that students often find it difficult to understand the logic behind abstract math problems. Usually, the assignment just states the facts without giving you any explanations as to the purpose of finding that famous X. Even though you do not understand the purpose of finding it, you still need to do it to pass the course. It is because math often operates with generalized abstractions. The algorithm of the reasoning process includes deduction in the sense that you go from analyzing general data to drawing specific conclusions. For some students, the process of operating abstractions can see too frustrating.

Meanwhile, quantitative reasoning (QR) is all about giving you specific context. You will mostly analyze real-world situations to come up with the correct answer. It is easier to solve a problem when you understand the logic behind it. Therefore, your task usually is to find the missing values or come up with a set of mathematical operations that will result in making a logical conclusion.

Popular Types of QR Problems

In the topic of quantitative reasoning, you may come across four types of problems: multiple-choice questions, numeric entries, and quantitative comparisons. Let's look at them in more detail.

As a student, you are familiar with the format of multiple-choice questions. Most probably, every exam includes this form of testing your knowledge. In terms of QR problems, you can face two options- questions that have only one correct answer and questions with more than one correct answer. As a rule, you will be asked to make several calculations to get the answer. In case the answer you got does not match any of the multiple-choice options, check if there are any mistakes.

The tricky part of this type of QR problem begins when you have to select several answers. How do you even understand that there is more than one correct answer? The tip here is to read the question carefully. If the question does not emphasize that you have to choose only one option, consider choosing several answers.

The format of numeric entries is quite challenging because there are no answer choices. You simply enter your answer in the corresponding field. It is impossible to check whether your answer is correct or not. You will often have a detailed description of the problem. So, use your logic to evaluate the correctness of your answer.

Quantitative comparisons might be the most difficult format of problems to solve. You will be given two or more encrypted values that you need to find and then compare. The tricky part here is to check whether this relation applies to all the possible situations.

Common Strategies for Solving QR Problems

It will be useful for you to learn about the possible approaches you can use to solve QR problems that include detailed descriptions. Here are some of them.

Rephrase a problem in your own words. Once you've read the problem, it is crucial to make sure you have a clear understanding of what numeric data you already have and what values you need to find. Use your own words to describe the problem.

Visualize. If you are more of a visual type of person, draw a picture or a scheme using the information you have. If you are not sure which strategy to use, visualization might help you find the right one.

Check the logic. Once you have the answer, put it in the context of the problem. Does it seem probable?

This is only one of the possible approaches. It gives you a set of organized actions of finding a solution to a problem.
