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. 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






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






3. Statement that two fractions or ratios are equal






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






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






6. Statement that two fractions or ratios are equal






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






8. Numeric value that does not change






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






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






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






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






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






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






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






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






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






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






21. Specific form of representing ratios - examples - a/b or 2/3 (denominator cannot be zero)






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






37. Specific form of representing ratios - examples - a/b or 2/3 (denominator cannot be zero)






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






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






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






41. 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.






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






43. 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






44. Numeric value that does not change






45. 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).






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






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






48. 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






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






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