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 quantity that does not vary






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






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






4. 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






5. 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






6. Same shape - but different size






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






8. The reciprocal of a number.






9. 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






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






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






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






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






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






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






16. A function whose graph is a straight line.






17. Numeric value that does not change






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






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






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






21. 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.






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






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






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






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






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






27. A quantity that does not vary






28. Statement that two fractions or ratios are equal






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






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






31. Same shape - but different size






32. 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)






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






34. 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






35. (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.






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






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






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






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






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






42. 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






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






44. 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






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






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






48. 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)






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






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