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






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






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






4. The reciprocal of a number.






5. Same shape - but different size






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






7. 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






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






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






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






11. 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).






12. 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.






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






14. 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






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






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






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






18. A quantity that does not vary






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






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






21. 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






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






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






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






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






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






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






28. A quantity that does not vary






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






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






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






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






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






34. A function whose graph is a straight line.






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






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






37. 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).






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






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






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






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






43. 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






44. A function whose graph is a straight line.






45. Numeric value that does not change






46. 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






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