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 relative greatness of positive and negative numbers






2. Plus






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






4. 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.






5. 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.






6. A number is divisible by 8 if






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






8. 2 -3 -4 -5 -6






9. 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






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






11. More than






12. A number is divisible by 3 if






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






14. Are used to indicate sets






15. A number is divisible by 9 if






16. The central problem of Diophantine geometry is to determine when a Diophantine equation has






17. Number X decreased by 12 divided by forty






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






19. First axiom of equality






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

21. 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.






22. Sixteen less than number Q






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






24. A number is divisible by 5 if its






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






26. A number is divisible by 4 if






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






28. 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:






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






30. 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.






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






32. The Arabic numerals from 0 through 9 are called






33. Product






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






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






36. 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.






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






38. 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.






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






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






41. 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.

46. Is any complex number that is a solution to some polynomial equation with rational coefficients; for example - every solution x of (say) is an algebraic number. Fields of algebraic numbers are also called algebraic number fields - or shortly number f






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






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.






49. Number T increased by 9






50. 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.
