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






2. 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.






3. A curve in the plane






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






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






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






7. 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






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






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

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






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






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






13. 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






14. 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.






15. A number is divisible by 4 if






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






17. Another way of encoding points in the complex plane other than using the x- and y-coordinates is to use the distance of a point P to O - the point whose coordinates are (0 - 0) (the origin) - and the angle of the line through P and O. This idea leads






18. Remainder






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






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






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






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






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






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. The square roots of a + bi (with b ? 0) are - where and where sgn is the signum function. This can be seen by squaring to obtain a + bi.






26. The set of all complex numbers is denoted by






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






28. 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






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






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






31. LAWS FOR COMBINING NUMBERS






32. Product






33. A number is divisible by 9 if






34. 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






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






36. Decreased by






37. A number is divisible by 2 if






38. Sixteen less than number Q






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






40. Number T increased by 9






41. 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.






42. 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






43. 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.






44. Total






45. 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.






46. Less than






47. 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.
