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 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






2. Statement that two fractions or ratios are equal






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






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






5. 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






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






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






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






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






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






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






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






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






15. Numeric value that does not change






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






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






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






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






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






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






22. 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






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






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






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






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






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






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






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






30. Same shape - but different size






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






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






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






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






36. A quantity that does not vary






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






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






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






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






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






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






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






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






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






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






49. 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






50. 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.
