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






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






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. Math phrase that uses variables - numbers and operation symbols






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






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






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






8. 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).






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






10. 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).






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






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






13. 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)






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






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






16. 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






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






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






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






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






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






22. (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.






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






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






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






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






27. A quantity that does not vary






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






29. Same shape - but different size






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






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






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






33. 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






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






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






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






37. 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






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






39. 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.






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






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






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






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






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






45. 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






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






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






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






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.
