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. 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.






2. 2 -3 -4 -5 -6






3. Decreased by






4. First axiom of equality






5. If the same quantity is subtracted from each of two equal quantities - the resulting quantities are equal. If equals are subtracted from equals - the results are equal.






6. The Arabic numerals from 0 through 9 are called






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






8. 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






9. 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.






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






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






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






13. The set of all complex numbers is denoted by






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






15. 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 -






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






17. Increased by






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






19. 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






20. 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.






21. More than






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






23. Quotient






24. One term (5x or 4)






25. Remainder






26. 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.






27. A number is divisible by 3 if






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






29. A number is divisible by 2 if






30. Number T increased by 9






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






32. 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 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.






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






36. 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






37. 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.






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