CLEP General Mathematics: Number Systems And Sets

Subjects : clep, 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. The relative greatness of positive and negative numbers






2. The finiteness or not of the number of rational or integer points on an algebraic curve






3. If two equal quantities are divided by the same quantity - the resulting quotients are equal. If equals are divided by equals - the results are equal.






4. The smallest of four sonsecutive whole numbers - the biggest of which is K+6






5. Number symbols






6. Addition of two complex numbers can be done geometrically by






7. Is called the real part of z - and the real number b is often called the imaginary part. By this convention the imaginary part is a real number - not including the imaginary unit: hence b - not bi - is the imaginary part. (Others - however call bi th






8. More than one term (5x+4 contains two)






9. Any number that la a multiple of 2 is an






10. In the Rectangular Coordinate System - On the vertical line - direction ________ is positive






11. A curve in the plane






12. Does not have an equal sign (3x+5) (2a+9b)






13. In particular - the square of the imaginary unit is -1: The preceding definition of multiplication of general complex numbers follows naturally from this fundamental property of the imaginary unit. Indeed - if i is treated as a number so that di mean






14. This law states that the product of three or more factors is the same regardless of the manner in which they are grouped. Negative signs require no special treatment in the application of this law.






15. Sum






16. A number is divisible by 4 if






17. Since the elements of the set {2 - 4 - e} are the same as the elements of{4 - 2 - e} - these two sets are said to be






18. Are used to indicate sets






19. This law can be applied to subtraction by changing signs so that all negative signs become number signs and all signs of operation are positive.






20. The greatest of 3 consecutive whole numbers - the smallest of which is F






21. No short method has been found for determining whether a number is divisible by






22. As the horizontal component - and imaginary part as vertical These two values used to identify a given complex number are therefore called its Cartesian - rectangular - or algebraic form.






23. The number touching the variable (in the case of 5x - would be 5)






24. A letter tat represents a number that is unknown (usually X or Y)






25. One asks whether there are any rational points (points all of whose coordinates are rationals) or integral points (points all of whose coordinates are integers) on the curve or surface. If there are any such points - the next step is to ask how many






26. As shown earlier - c - di is the complex conjugate of the denominator c + di.






27. One term (5x or 4)






28. In the Rectangular Coordinate System - On the vertical line - direction _______ is negative






29. The central problem of Diophantine geometry is to determine when a Diophantine equation has






30. The Arabic numerals from 0 through 9 are called






31. 2 -3 -4 -5 -6






32. Are not necessary. That is - the elements of {2 - 2 - 3 - 4} are simply {2 - 3 - and 4}






33. This law combines the operations of addition and multiplication. The distribution of a common multiplier among the terms of an additive expression.






34. Decreased by






35. The base which is most commonly used is ten - and the system with ten as a base is called the decimal system (decem is the Latin word for ten). Any number is assumed - unless indicated - to be a






36. Viewed in this way the multiplication of a complex number by i corresponds to rotating a complex number






37. This formula can be used to compute the multiplicative inverse of a complex number if it is given in






38. Product






39. The place value which corresponds to a given position in a number is determined by the






40. This law states that the product of two or more factors is the same regardless of the order in which the factors are arranged. Negative signs require no special treatment in the application of this law.






41. First axiom of equality






42. A number is divisible by 2 if






43. The number without a variable (5m+2). In this case - 2






44. This law can be applied to subtraction by changing signs in such a way that all negative signs are treated as number signs rather than operational signs.That is - some of the addends can be negative numbers.






45. In the Rectangular Coordinate System - the direction to the left along the horizontal line is






46. One asks whether there are any rational points (points all of whose coordinates are rationals) or integral points (points all of whose coordinates are integers) on the curve or surface. If there are any such points - the next step is to ask how many






47. Subtraction






48. Begin by taking out the smallest factor If the number is even - take out all the 2's first - then try 3 as a factor
