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






2. Statement that two fractions or ratios are equal






3. A quantity that does not vary






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






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






6. Numeric value that does not change






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






8. 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






9. A function whose graph is a straight line.






10. 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






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






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






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






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






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






16. The reciprocal of a number.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






35. 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






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






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






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






39. 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






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






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






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






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






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






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

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






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






49. 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.
