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. 1. round the numbers being multiplied to one more place than it is being asked. 2. Multiply the rounded off numbers 3. round of product to desired number of places






2. The whole equals






3. Parallel and never intersect - they have no solution at all - they are parallel with the same slope






4. Is - as - was - has - cost






5. A/A¹ = B/B¹= C/C¹






6. Are the lines that bisect and are perpendicular to each of the three sides. The point where they meet is the center of the circumscribed circle.






7. V3






8. Wx>wy






9. ? if a side < b side - then






10. x>0 and y>0 or x<0 and y<0






11. Less than 90°






12. x more than y






13. Integer is divisible by 2






14. If ?B > ?A - then






15. 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.






16. N= number of objects (order matters!!!) k= rate at a time nPk= n!/(n-k)! (remember to cancel common numbers)






17. Write down every member that the two sets have in common. The intersection of the sets A and B is a set written AnB






18. Angle whose sides are two chords. The vertex of the angles lies on the circumference of the circle. The number of degrees of the angle is equal to 1/2 the intercepted arc






19. Ax= by + C






20. The point where the line crosses the y-axis - x will always = 0 in this case






21. If two lines are parallel - the slope of one is






22. Area= 1/2bh perimeter= a + b+ c hypotenuse= c²= b²+a²






23. The decrease from x to y






24. If under the operation - any two members of the set constitute an element of the set ( * the product of the elements multiplied by themselves must also be an element of the set*)






25. x + (n/100)x






26. If an equation can be put into the form y= mx +b - then






27. (x+y)(x+y)= (x+y)²






28. The point where the line crosses the x-axis - y will always = 0 in this case






29. 1/x + 1/y x -y ? 0






30. Which - what






31. 7-24-25






32. Any integer is divisible by 10 - if

43. If two lines are perpendicular - the slope of one is the






44. Write down every member in one or both of the sets - the union of two sets is a new set. the union of set A and B is written as A?B






45. In transversals
