# What’s Tested on the DAT: Quantitative Reasoning

The Quantitative Reasoning section of the DAT is designed to test the math skills that will be required in dental school. The section contains 40 multiple-choice questions, and you will have 45 minutes to complete it. A basic on-screen calculator similar to the one below will be available only in this section. It can be opened by clicking the “Calculator” button at the bottom of the screen. The calculator can add, subtract, multiply, and divide as well as take square roots, percentages, and reciprocals. Note that the calculator cannot perform the complex functions of a scientific or graphing calculator. You also can’t input to the calculator by typing and instead will need to click every number and operation you want to perform, which can be quite time consuming and lead to making mistakes. For these reasons, avoid using the calculator as much as possible and instead use mental math and quick scratch-work calculations, saving the calculator for the rare questions with difficult multiplication or long division. Developing your ability to complete calculations without a calculator will also be helpful for the Survey of Natural Sciences since you won’t have access to a calculator during any of that section.

### Quantitative Reasoning Content

The American Dental Association (ADA) has published a DAT User’s Manual on their Dental Admission Test (DAT) page that establishes what content can be tested on the DAT. The following outlines the exact content you will need to know for the Quantitative Reasoning section, and the numbers in parentheses reflect how many questions that primarily test that subject are likely to be on any given DAT administration. Note that many questions require knowledge from more than one content area listed, especially the Word Problems category, which accounts for 25% of the section. Algebra (9)

• Equations and Expressions
• Inequalities
• Exponential Notation
• Absolute Value
• Ratios and Proportions
• Graphical Analysis

Numerical Calculations (6)

• Fractions and Decimals
• Percentages
• Approximations
• Scientific Notation

Conversions (3)
• Temperature
• Time
• Weight
• Distance

Probability and Statistics (4)

Geometry (4)

Trigonometry (4)

Word Problems (10)

### Quantitative Reasoning Strategies

Since you will only have just over one minute for each math question, it’s important to be able to use efficient test-taking strategies to ensure you have enough time to complete each question. Many students find the timing of the Quantitative Reasoning section to be the most difficult to manage during the DAT, and this is compounded by the fact that Quantitative Reasoning is the last section, which means many students are exhausted by that point.
