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. LAWS FOR COMBINING NUMBERS






2. 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.






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






4. 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.






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






6. This law states that the sum of two or more addends is the same regardless of the order in which they are arranged. Means to change - substitute or move from place to place.






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






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






9. 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.






10. 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






11. Sum






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






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






14. 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.






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

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 X decreased by 12 divided by forty






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






19. 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.






20. Quotient






21. The objects in a set have at least






22. The Arabic numerals from 0 through 9 are called






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






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






25. Less than






26. Increased by






27. 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






28. Total






29. 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.






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






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






32. Number symbols






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






34. A number is divisible by 4 if






35. 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






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






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






38. 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.






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






40. A number is divisible by 2 if
