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






2. Quotient






3. Any number that is exactly divisible by a given number is a






4. Are used to indicate sets






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






6. Sum






7. A number that has factors other than itself and 1 is a






8. 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






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






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






11. The objects or symbols in a set are called Numerals - Lines - or Points






12. 2 -3 -4 -5 -6






13. A branch of geometry studying more general reflections than ones about a line - can also be expressed in terms of complex numbers.






14. If the same quantity is subtracted from each of two equal quantities - the resulting quantities are equal. If equals are subtracted from equals - the results are equal.






15. G - E - M - A Grouping - Exponents - Multiply/Divide - Add/Subtract






16. The sum of two complex numbers A and B - interpreted as points of the complex plane - is the point X obtained by building a parallelogram three of whose vertices are O - A and B. Equivalently - X is the point such that the triangles with vertices O -






17. Total






18. Any number that is not a multiple of 2 is an






19. This law states that the sum of two or more addends is the same regardless of the order in which they are arranged. Means to change - substitute or move from place to place.






20. The relative greatness of positive and negative numbers






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






22. More than






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






24. 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






25. The set of all complex numbers is denoted by






26. A number is divisible by 5 if its






27. A number is divisible by 4 if






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






29. Product






30. The number of digits in an integer indicates its rank; that is - whether it is 'in the hundreds -' 'in the thousands -' etc. The idea of ranking numbers in terms of tens - hundreds - thousands - etc. - is based on the






31. Allow the variables in f(x -y) = 0 to be complex numbers; then f(x -y) = 0 defines a 2-dimensional surface in (projective) 4-dimensional space (since two complex variables can be decomposed into four real variables - i.e. - four dimensions). Count th






32. Product of 16 and the sum of 5 and number R






33. A number is divisible by 3 if






34. Allow for solutions to certain equations that have no real solution: the equation has no real solution - since the square of a real number is 0 or positive.






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






36. 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.






37. Integers greater than zero and less than 5 form a set - as follows:






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






39. A number is divisible by 9 if






40. 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






41. Subtraction






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






43. If a factor of a number is prime - it is called a






44. A number is divisible by 2 if






45. A number is divisible by 6 if it is






46. This law states that the sum of three or more addends is the same regardless of the manner in which they are grouped. suggests association or grouping.






47. Studies algebraic properties and algebraic objects of interest in number theory. (Thus - analytic and algebraic number theory can and do overlap: the former is defined by its methods - the latter by its objects of study.) A key topic is that of the a
