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. Math phrase that uses variables - numbers and operation symbols






2. Same shape - but different size






3. 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.






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






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






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






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






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






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






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






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






12. 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






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






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






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






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






17. (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.






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






19. The reciprocal of a number.






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






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






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






23. 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.






24. 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






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






26. A quantity that does not vary






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






28. Statement that two fractions or ratios are equal






29. A quantity that does not vary






30. 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).






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






32. 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.






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






34. 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)






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






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






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






38. A function whose graph is a straight line.






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






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






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






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

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






45. (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.






46. Statement that two fractions or ratios are equal






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