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






2. 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)






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






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






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






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






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






9. (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.






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






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






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






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






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






15. A quantity that does not vary






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






17. 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).






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






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






20. 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






21. 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






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






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






24. Numeric value that does not change






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






26. Numeric value that does not change






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






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






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






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






31. 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






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






33. 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.






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. Expressions that contain the same variables to the same power






37. Same shape - but different size






38. (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.






39. A quantity that does not vary






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






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






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






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






44. 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).






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






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






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






48. Statement that two fractions or ratios are equal






49. A function whose graph is a straight line.






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