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 number is divisible by 2 if






2. Are often studied as extensions of smaller number fields: a field L is said to be an extension of a field K if L contains K. (For example - the complex numbers C are an extension of the reals R - and the reals R are an extension of the rationals Q.)






3. 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






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






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






6. A number is divisible by 9 if






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






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






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






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






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






12. 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






13. The Arabic numerals from 0 through 9 are called






14. Sum






15. 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.






16. Plus






17. 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.






18. Number symbols






19. 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






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






21. 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






22. The objects in a set have at least






23. 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 -






24. Number X decreased by 12 divided by forty






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






26. 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.






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






28. Sixteen less than number Q






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






30. 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.






31. 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






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






33. 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






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






35. LAWS FOR COMBINING NUMBERS






36. Decreased by






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






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

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






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






41. 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
