Subjects : math, algebra
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 mathematical phrase involving one or more terms and operations






2. Fractions that name the same amount or part - 1/2 and 2/4 are equivalent fractions






3. A fraction in which the numerator is greater than or equal to the denominator; examples: 5/5 or 7/4






4. A number that can be written as a/b where a and b are integers - but b is not equal to 0; an integer or a fraction; examples: 6 can be expressed as 6/1; 0.5 can be expressed as 1/2.






5. A function whose graph is a straight line.






6. A decimal number that ends or terminates; example: 6.75






7. A decimal in which one or more digits repeat infinitely; The repeating portion of the decimal is shown with a short line drawn over the repeating numbers.






8. The ratio of dimensions of the new image to those of the original figure






9. An ordered list or numbers; example: 2 -4 -6 -8 -10...






10. A property indicating a special way in Which multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses - such as a(b + c) = ab + ac; ex: 4(3 + 8)






11. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 9.






12. The x- and y-axes divide the coordinate plane into four regions. Each region is called a quadrant.






13. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).






14. A method of measurement that uses formulas - similar figures - and/or proportions.






15. A mathematical phrase involving one or more terms and operations






16. A diagram of an object in which the dimensions are in proportion to the actual dimensions of the object.






17. For any number a and b - a + b = b + a






18. (mathematics) one of a pair of numbers whose product is 1: the reciprocal of 2/3 is 3/2; a fraction that has been flipped. The reciprocal of 3/4 is 4/3.






19. Math phrase that uses variables - numbers and operation symbols






20. Any of the numbers (or symbols) that form a product when multiplied together; 3 is a factor of 9






21. The point where the x-axis and y-axis intersect on the coordinate plane; (0 - 0).






22. An input-output relationship that has exactly one output for each input; An equation written with two variables where only one output exists for each input; example: y = 2x +1






23. The number that indicates how many times the base is used as a factor






24. The ratio between the size of something and a representation of it






25. Letter that represents a number; variable amounts may change






26. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






27. The distance from zero to the real number on a number line.






28. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






29. A quantity that does not vary






30. An expression that contains only numbers and operations (2 3) + 1

32. A quantity obtained by multiplication; the answer to a multiplication problem






33. A quantity that does not vary






34. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






35. A function whose graph is a straight line.






36. The plane formed by 2 number lines that intersect at their zero points dividing the plane into 4 quadrants; A coordinate system formed by the intersection of a horizontal number line - called the x-axis - and a vertical number line - called the y-axi






37. A number written as the product of its prime factors; examples: 10 = 2 5 - 24 = 2^3 3 (^3 means the 3 is written smaller and to the upper right of 2).

40. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






41. States that changing grouping of factors does not change the product. (ab)c = a(bc); ex: (2 6) 7 = 2 (6 7)






42. The order in which operations in an expression to be evaluated are carried out. 1. parentheses 2. exponets 3. multiplication and divison 4. addition and subtraction






43. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






44. All rational or irrational numbers; real numbers can be represented on the real number line






45. The operation which undoes an operation - the opposite operation: subtraction is the inverse of addition - addition is the inverse of subtraction; division is the inverse of multiplication - multiplication is the inverse of division - square root is
