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. Letter that represents a number; variable amounts may change






2. 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






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






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






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






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






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






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






9. Statement that two fractions or ratios are equal






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






11. 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






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






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






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






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






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






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






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






20. 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






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






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






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






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






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






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






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






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






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






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






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






32. Numeric value that does not change






33. (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.






34. The reciprocal of a number.






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






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






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






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






39. A function whose graph is a straight line.






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






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






42. The reciprocal of a number.






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






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






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






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






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






48. 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.
