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






2. The distance from zero to the real number on a number line.






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






4. Numeric value that does not change






5. 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.






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






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






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






9. 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






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






11. 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).






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






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






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. Math phrase that uses variables - numbers and operation symbols






16. The distance from zero to the real number on a number line.






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






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






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






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






21. 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






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






23. The reciprocal of a number.






24. 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






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






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






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






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






29. A function whose graph is a straight line.






30. Numeric value that does not change






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






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






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






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






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






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






38. Statement that two fractions or ratios are equal






39. The reciprocal of a number.






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






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






42. 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)






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






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






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






46. Same shape - but different size






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






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






49. A quantity that does not vary






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