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






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






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






4. A curve in the plane






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






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. A number is divisible by 9 if






8. A number is divisible by 8 if






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






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






11. 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






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






13. Decreased by






14. 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.






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






16. 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.






17. The objects or symbols in a set are called Numerals - Lines - or Points






18. A number is divisible by 6 if it is






19. Number symbols






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






21. 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.






22. The Arabic numerals from 0 through 9 are called






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






24. Less than






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






27. 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.






28. In the Rectangular Coordinate System - the direction to the left along the horizontal line is






29. Sixteen less than number Q






30. The objects in a set have at least






31. One term (5x or 4)






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






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






34. This formula can be used to compute the multiplicative inverse of a complex number if it is given in






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






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. 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






38. First axiom of equality






39. 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






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






41. 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






42. Increased by






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






44. 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






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

48. More than






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






50. 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
