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






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






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






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






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






6. 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.






7. 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).






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






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






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






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






12. 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.






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






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






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






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






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






19. Numeric value that does not change






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






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






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






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






24. Same shape - but different size






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






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






27. 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






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






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






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






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






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






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






34. A quantity that does not vary






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






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






37. Numeric value that does not change






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






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






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






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






43. The reciprocal of a number.






44. 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






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






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






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






48. The reciprocal of a number.






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






50. (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.
