Middle Grade Math And Basic Algebra

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






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






4. The number obtained by division; the ratio of two quantities to be divided; the answer to a division problem






5. A real number that cannot be expressed as a rational number






6. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






7. 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).






8. 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.






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






10. (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.






11. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






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






13. Changing the grouping of terms will not change the sum - (a + b) + c = a + (b + c); ex: (5+3) + 1 = 5 + (3 + 1)






14. The product of a quantity by an integer; example 24 is a multiple of 3 and 8






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






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






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






18. 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






19. The Zero Property of Addition. Adding 0 to a number leaves it unchanged; ex: 67+0=67 - 67+0=67






20. A symbol (like x or y) that is used in mathematical or logical expressions to represent a variable quantity; in the expression 2x + 3 - x is the variable






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






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






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






24. (mathematics) one of a pair of numbers whose sum is zero






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






26. A comparison of two quantities - may be directly represented by numbers and or variables






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






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






29. A pair of numbers that can be used to locate a point on a coordinate plane.






30. A real number that cannot be expressed as a rational number






31. An equation whose solutions form a straight line on a coordinate plane; example: y = 3x - 1






32. The reciprocal of a number.






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






34. The number obtained by division; the ratio of two quantities to be divided; the answer to a division problem






35. Expressions that contain the same variables to the same power






36. Specific form of representing ratios - examples - a:b or 2:3






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






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






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






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






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






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






43. A quantity that does not vary






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






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






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






47. A pair of numbers that can be used to locate a point on a coordinate plane.






48. A comparison of two quantities - may be directly represented by numbers and or variables






49. Statement that two fractions or ratios are equal






50. 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
