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. Any number squared or raised to an even power is






2. A closed plane whose sides are straight lines. The sum of the angles is equal to 180(n-2) - where n is the number of sides.






3. Area= 1/2?r2 length= 1/2?d= ?r perimeter= d(1/2? +1)






4. Intersect at only one point - the point is the only solution to the pair of equations






5. One angle is equal 90° and the other two angles are equal to the sum of 90°






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






7. x(y+z)






8. Have two equal sides and two equal angles formed by the equal sides and the unequal side.






9. 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.






10. Less than 90°






11. (amount of decrease/original amount) x 100






12. A subset of a set is






13. Side a +side b of a ? is






14. Any integer is divisible by 6 if






15. Is - as - was - has - cost






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






17. x/100






18. When the elements of a set are ordered pairs






19. Then their intersection is the null or empty set - written as Ø






20. ?






21. Ax= by + C






22. Product of an even number and any other number is






23. If ?B > ?A - then






24. The case where the two equations are equivalent (just two different forms of the same mathematical relation). Any point that satisfies either of the equations - automatically satisfies both






25. 180°






26. Area= s² perimeter= 4s






27. 1/2bh






28. x older than y






29. z>y






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






31. M= y2-y1/x2-x1






32. Volume= 4/3?r² surface area= 4?r²






33. Is the set of the first components of the ordered pairs.






34. M=number of favorable ways n= total number of ways (two events occurring is the prob of the first times the prob of the second)






35. xw> yz






36. Are the lines drawn from each vertex to the midpoint of its opposite side. they cross at a point that divides each individual ______into two parts.






37. x>z






38. The distance between two parallel lines or from a point to a line always means






39. The increase from x to y






40. Angles directly across each other are equal






41. x²






42. 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






43. 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)






44. 1. solve the equation or inequality 2. use ONLY the solutions which satisfy the condition required - the set of all x such that x is greater than or equal to 10 R= {x: x=10}






45. Is a subset of every set
