Quantitative reasoning refers to a student's ability in understanding the elements of number theory, and applying them in solving number problems. The test includes the following three sub-categories:

• Quantitative relationship: Comparison of two quantities as greater, less or equal.
• Number series: Finding the number pattern, and apply it to find the next number following the pattern.
• Equation building: Building an equation using given numbers and operators in any order to make a number in the choices.
