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. Number X decreased by 12 divided by forty






2. Sum






3. 2 -3 -4 -5 -6






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






5. First axiom of equality






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






7. A number is divisible by 5 if its






8. Less than






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






10. Decreased by






11. 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.






12. Sixteen less than number Q






13. The set of all complex numbers is denoted by






14. A curve in the plane






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






16. 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:






17. Number T increased by 9






18. Total






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






20. 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






21. Product






22. 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






23. 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






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






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






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






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






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






29. 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.






30. One term (5x or 4)






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






32. 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






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






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






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






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






37. Increased by






38. A number is divisible by 2 if






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






40. Are used to indicate sets






41. 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






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

44. Remainder






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






46. 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.






47. The Arabic numerals from 0 through 9 are called






48. 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
