The quantitative section of the GMAT measures the ability to **reason** quantitatively, **solve** quantitative problems, and **interpret** graphic data.

Questions require knowledge of arithmetic, elementary **algebra** and commonly known concepts of **geometry**.

There are two types of quantitative questions: problem solving and **data sufficiency**.

Scores range from 0 to 60, although they only report scores between **11 and 51**.

Problem solving questions are designed to test the ability to reason quantitatively and solve quantitative problems.

**Data sufficiency questions** are designed to measure the ability to **analyze** a quantitative problem, **recognize** which data are relevant and **determine** at what point there is enough data to **solve** the problem.
