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






2. 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






3. The number without a variable (5m+2). In this case - 2






4. Decreased by






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






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






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






8. The numbers which are used for counting in our number system are sometimes called






9. 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.






10. 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






11. 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.






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






13. Sixteen less than number Q






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






15. 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.






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






17. The relative greatness of positive and negative numbers






18. More than






19. A number is divisible by 9 if






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






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






22. 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






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






24. 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






25. The set of all complex numbers is denoted by






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






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






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






29. 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.






30. A number is divisible by 2 if






31. 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






32. The Arabic numerals from 0 through 9 are called






33. In particular - the square of the imaginary unit is -1: The preceding definition of multiplication of general complex numbers follows naturally from this fundamental property of the imaginary unit. Indeed - if i is treated as a number so that di mean






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






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






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

43. 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
