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






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






3. 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.






4. 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






5. LAWS FOR COMBINING NUMBERS






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






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






8. 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






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






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






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






12. Any number that is not a multiple of 2 is an






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






14. 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.






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






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






17. 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.)






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






19. Total






20. 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.






21. 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.






22. Sum






23. Quotient






24. 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.






25. Number symbols






26. 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






27. 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






28. 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.






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






30. 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






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






32. 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:






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






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






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






36. 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.






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






38. Plus






39. If two equal quantities are divided by the same quantity - the resulting quotients are equal. If equals are divided by equals - the results are equal.






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