GRE Math Strategies

Subjects : gre, math
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. If two lines are parallel - the slope of one is






2. Any integer is divisible by 4 - if






3. The sume of x and y






4. 5-12-13






5. In a triangle - if ?c(interior angle in triangle) and ?d(exterior angle out of triangle) are supplmentary angles - than ?a and ?b are remote interior angles to <d - thus - a +b+c = 180 (triangle) c+d = 180 (supplementary angles)






6. 1-v3- 2 (90-30-60)






7. N= combinations taken (order does not matter) r= rate at a time nCr or C(n -r) = (n)!/(r)! (remember to cancel out common numbers)






8. y<x






9. 1. round each number being added to one more place than it is being asked. 2. add the rounded numbers. 3. round off the sum to the desired number of places






10. Is drawn from the vertices perpendicular to the opposite sides. The lengths of these lines are useful in calculating the area of the trinagle since the area of the triangle is 1/2bh and the height and the _____are the same.
