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. Plus






2. Decreased by






3. Are used to indicate sets






4. Has an equal sign (3x+5 = 14)






5. Implies a collection or grouping of similar - objects or symbols.






6. The set of all complex numbers is denoted by






7. If two equal quantities are multiplied by the same quantity - the resulting products are equal. If equals are multiplied by equals - the products are equal.






8. Number X decreased by 12 divided by forty






9. Less than






10. A curve in the plane






11. 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






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






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






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






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






16. 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.






17. The numbers which are used for counting in our number system are sometimes called






18. 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






19. 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.






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






21. 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.






22. 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






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






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






25. More than






26. The defining characteristic of a position vector is that it has






27. Quotient






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






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






30. The objects in a set have at least






31. In terms of its tools - as the study of the integers by means of tools from real and complex analysis - in terms of its concerns - as the study within number theory of estimates on size and density - as opposed to identities.






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






33. Any number that can be divided lnto a given number without a remainder is a






34. Total






35. If z is a real number (i.e. - y = 0) - then r = |x|. In general - by Pythagoras' theorem - r is the distance of the point P representing the complex number z to the origin.






36. 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 -






37. 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.






38. Increased by






39. A number is divisible by 3 if






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






41. 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






42. These are emphasised in a complex number's polar form and it turns out notably that the operations of addition and multiplication take on a very natural geometric character when complex numbers are viewed as position vectors:






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






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






45. 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.






46. A number is divisible by 8 if






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






48. 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
