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. Same shape - but different size






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






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






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






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






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






7. A quantity that does not vary






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






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






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






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






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






13. Same shape - but different size






14. Numeric value that does not change






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






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. The reciprocal of a number.






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






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






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






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






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






23. 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.






24. 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






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






26. 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






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






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






29. The reciprocal of a number.






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






31. A quantity that does not vary






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






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






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






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






36. 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






37. Expressions that contain the same variables to the same power






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






39. Expressions that contain the same variables to the same power






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






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






42. 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






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






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






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






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






47. 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)
