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. (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.






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






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






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






6. Same shape - but different size






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






8. 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)






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






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






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






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






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






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






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






16. 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






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






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






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






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






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






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






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






24. Statement that two fractions or ratios are equal






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






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






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






28. 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






29. 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).






30. Numeric value that does not change






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






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






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






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






35. A quantity that does not vary






36. The reciprocal of a number.






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






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






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






40. 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






41. 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






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






43. 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






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






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






46. 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.






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






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