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 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).






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






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






4. (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.






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






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






7. 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






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






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






10. 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






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






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






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






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






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






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






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






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






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






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






21. 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.






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






23. A number multiplied by a variable in an algebraic expression; a constant number that serves as a measure of some property or characteristic






24. 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






25. Same shape - but different size






26. 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.






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






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






29. 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






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






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






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






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






34. Same shape - but different size






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






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






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






38. 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).






39. The reciprocal of a number.






40. 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






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






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






44. A function whose graph is a straight line.






45. A quantity that does not vary






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






47. Statement that two fractions or ratios are equal






48. 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






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






50. Statement that two fractions or ratios are equal
