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. 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






2. A number is divisible by 4 if






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






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

5. Number T increased by 9






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. 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






8. 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






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






10. The Arabic numerals from 0 through 9 are called






11. A letter tat represents a number that is unknown (usually X or Y)






12. 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.






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






14. A number is divisible by 3 if






15. LAWS FOR COMBINING NUMBERS






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






17. 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.






18. This law states that the sum of three or more addends is the same regardless of the manner in which they are grouped. suggests association or grouping.






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






20. A number is divisible by 6 if it is






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






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






23. 2 -3 -4 -5 -6






24. 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






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






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






27. 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 -






28. Number symbols






29. Sum






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






31. 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.






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






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






34. A number is divisible by 8 if






35. 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.






36. Decreased by

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






42. Remainder






43. These are emphasised in a complex number's polar form and it turns out notably that the operations of addition and multiplication take on a very natural geometric character when complex numbers are viewed as position vectors:






44. A curve in the plane






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






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






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






48. 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.
