CLEP General Math: Number Sense - Patterns - Algebraic Thinking

Subjects : clep, math, algebra
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. Means approximately equal.






2. If grouping symbols are nested






3. Let a and b be whole numbers. Then a is _______________ by b if and only if the remainder is zero when a is divided by b. In this case - we say that 'b is a divisor of a.'






4. Writing Mathematical equations - arrange your work one equation






5. In this type of geometry the angles of a triangle add up to less than 180 degrees. In such a system - one has to replace the parallel postulate with a version that admits many parallel lines.






6. If its final digit is a 0 or 5.






7. A way to measure how far away a given individual result is from the average result.






8. This result relates conserved physical quantities - like conservation of energy - to continuous symmetries of spacetime.

9. You must let your readers know what each variable in your problem represents. This can be accomplished in a number of ways: Statements such as 'Let P represent the perimeter of the rectangle.' - Labeling unknown values with variables in a table - Lab






10. Is the length around an object. Used to calculate such things as fencing around a yard - trimming a piece of material - and the amount of baseboard needed for a room.It is not necessary to have a formula since it is always just calculated by adding t






11. Every solution to a word problem must include a carefully crafted equation that accurately describes the constraints in the problem statement.






12. Mathematical statement that equates two mathematical expressions.






13. Every whole number can be uniquely factored as a product of primes. This result guarantees that if the prime factors are ordered from smallest to largest - everyone will get the same result when breaking a number into a product of prime factors.






14. 1. Parentheses (or any grouping symbol {braces} - [square brackets] - |absolute value|)

15. Arise from the attempt to measure all quantities with a common unit of measure.






16. The inverse of multiplication






17. This model is at the forefront of probability research. Mathematicians use it to model traffic patterns in an attempt to understand flow rates and gridlock - among other things.






18. Multiplication is equivalent to






19. Instruments produce notes that have a fundamental frequency in combination with multiples of that frequency known as partials or overtones






20. This means that for any two magnitudes - one should always be able to find a fundamental unit that fits some whole number of times into each of them (i.e. - a unit whose magnitude is a whole number factor of each of the original magnitudes)






21. An important part of problem solving is identifying






22. A way to extrinsically measure the curvature of a surface by looking at a given point and finding the contour line with the greatest curvature and the contour line with the least curvature.






23. Index p radicand






24. The multitude concept presented numbers as collections of discrete units - rather like indivisible atoms.






25. A topological invariant that relates a surface's vertices - edges - and faces.






26. Used to display measurements. The measurement was taken is placed on the horizontal axis - and the height of each bar equals the amount during that year.






27. Solving Equations






28. A point in one dimension requires only one number to define it. The number line is a good example of a one-dimensional space.






29. A · 1/a = 1/a · a = 1






30. You must always solve the equation set up in the previous step.






31. Codifies the 'average behavior' of a random event and is a key concept in the application of probability.






32. (a + b) + c = a + (b + c)






33. The process of taking a complicated signal and breaking it into sine and cosine components.






34. If we start with a number x and multiply by a number a - then dividing the result by the number a returns us to the original number x. In symbols - a






35. If a represents any whole number - then a






36. Two equations if they have the same solution set.






37. A point in three-dimensional space requires three numbers to fix its location.






38. Add and subtract






39. TA model of a sequence of random events. Each marble that passes through the system represents a trial consisting of as many random events as there are rows in the system.






40. Three is the common property of the group of sets containing three members. This idea is called '__________ -' which is a synonym for 'size.' The set {a -b -c} is a representative set of the cardinal number 3.






41. This important result says that every natural number greater than one can be expressed as a product of primes in exactly one way.






42. Is a path that visits every node in a graph and ends where it began.






43. Some numbers make geometric shapes when arranged as a collection of dots - for example - 16 makes a square - and 10 makes a triangle.






44. A






45. The expression a/b means






46. 1. Any two points can be joined by a straight line. 2. Any straight line segment can be extended indefinitely in a straight line. 3. Given any straight line segment - a circle can be drawn having the segment as radius and one endpoint as center. 4. A

47. If its final digit is a 0.






48. The four-dimensional analog of the cube - square - and line segment. A hypercube is formed by taking a 3-D cube - pushing a copy of it into the fourth dimension - and connecting it with cubes. Envisioning this object in lower dimensions requires that






49. If a and b are any whole numbers - then a






50. W = {0 - 1 - 2 - 3 - 4 - 5 - . . .} is called
