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 3 if






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






3. Consists of all numbers of the form - where a and b are rational numbers and d is a fixed rational number whose square root is not rational.






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






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






6. Plus






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






8. 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 -






9. Less than






10. 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






11. 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.






12. The real and imaginary parts of a complex number can be extracted using the conjugate:






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






14. The objects in a set have at least






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






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






17. 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






18. 2 -3 -4 -5 -6






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






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






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






22. Increased by






23. 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






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






25. 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.






26. 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






27. 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






28. Number T increased by 9






29. In terms of its tools - as the study of the integers by means of tools from real and complex analysis - in terms of its concerns - as the study within number theory of estimates on size and density - as opposed to identities.






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






31. 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.






32. Quotient






33. 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
