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. Total






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






3. A number is divisible by 2 if






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






5. Remainder






6. 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.






7. 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.






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






9. First axiom of equality






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






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






12. Increased by






13. The set of all complex numbers is denoted by






14. 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.






15. 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






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






17. A curve in the plane






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






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






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






21. 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.






22. A number is divisible by 9 if






23. 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






24. Sum






25. Work on the problem of general polynomials ultimately led to the fundamental theorem of algebra -






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






27. An equation - or system of equations - in two or more variables defines






28. The objects in a set have at least






29. Product






30. A number is divisible by 8 if






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






32. In the Rectangular Coordinate System - the direction to the right along the horizontal line is






33. A number is divisible by 6 if it is






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






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






36. Consists of all numbers of the form - where a and b are rational numbers and d is a fixed rational number whose square root is not rational.






37. 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.






38. Quotient






39. Number X decreased by 12 divided by forty






40. Are often studied as extensions of smaller number fields: a field L is said to be an extension of a field K if L contains K. (For example - the complex numbers C are an extension of the reals R - and the reals R are an extension of the rationals Q.)






41. 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.






42. 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.






43. 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






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






45. The Arabic numerals from 0 through 9 are called






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






47. More than






48. One term (5x or 4)






49. 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






50. The real and imaginary parts of a complex number can be extracted using the conjugate:
