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 sum is zero






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






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






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






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






6. A quantity that does not vary






7. Statement that two fractions or ratios are equal






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






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






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






11. 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






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






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






14. 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






15. 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.






16. (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.






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






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






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






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






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






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






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






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






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






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






28. 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






29. 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






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






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






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






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






34. 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).






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






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






37. 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






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






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






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






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






42. The reciprocal of a number.






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






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






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






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






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






48. A function whose graph is a straight line.






49. Numeric value that does not change






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