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. 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.






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






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






4. 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






5. A number is divisible by 2 if






6. 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






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. 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






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






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






11. The relative greatness of positive and negative numbers






12. Quotient






13. 2 -3 -4 -5 -6






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






15. A number is divisible by 6 if it is






16. One term (5x or 4)






17. A number is divisible by 9 if






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






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. Are used to indicate sets






21. Increased by






22. 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






23. 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






24. 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.






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. 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 -






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






28. 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






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






30. The complex conjugate of the complex number z = x + yi is defined to be x - yi. It is denoted or . Geometrically - is the

33. A form of coding in which the value of each digit of a number depends upon its position in relation to the other digits of the number. The convention used in our number system is that each digit has a higher place value than those digits to the right






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






35. LAWS FOR COMBINING NUMBERS






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






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






38. 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.






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






40. 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.






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






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






43. 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.






44. A number that has no factors except itself and 1 is a






45. Is a number that can be expressed in the form where a and b are real numbers and i is the imaginary unit - satisfying i2 = -1. For example - -3.5 + 2i is a complex number. It is common to write a for a + 0i and bi for 0 + bi. Moreover - when the imag
