There are four math question types on the GRE. They are:
- Quantitative Comparison
- Problem Solving
- Data Interpretations
- Numeric Entry
The quantitative comparison questions are unlike any you've ever see, and there are several tactics that you should employ when answering such questions. The problem solving questions on the math section of the GRE are the standard "word problem" questions that you have most likely seen throughout your schooling. The data interpretation questions on the GRE require you to answer questions based on your interpretation of graphical or tabular data. The data interpretation questions are unique in that in most cases you can approximate your calculations and still arrive at the correct answer -- this is because interpreting graphical data is tricky, and exact values for charts are not always provided. Finally, Numeric Entry questions are similar to the problem solving questions. However, unlike the other math problems on the GRE where you choose from 4 or 5 provided choices, the numeric entry questions require you to provide the answer to the question using the keyboard -- you input your answer into either a single box or into two boxes if the answer is in the form of a ratio.
