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






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






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






4. 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






5. Plus






6. 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.






7. 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.






8. 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.






9. More than






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






11. One term (5x or 4)






12. Remainder






13. Number symbols






14. A number is divisible by 5 if its






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






16. 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.






17. The objects in a set have at least






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






19. 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






20. 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






21. Sum






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






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






24. The relative greatness of positive and negative numbers






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






26. 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.






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






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






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






30. 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






31. Subtraction






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






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






34. The set of all complex numbers is denoted by






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






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






37. A number is divisible by 3 if






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






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






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






41. Decreased by






42. A number is divisible by 2 if






43. 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.






44. 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






45. 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.






46. 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
