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






2. A quantity that does not vary






3. 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






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






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






6. 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.






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






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






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






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






11. 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)






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






13. The reciprocal of a number.






14. Statement that two fractions or ratios are equal






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






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






17. (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.






18. Numeric value that does not change






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






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






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






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






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






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






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






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






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






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






29. 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






30. 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)






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






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






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






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






35. 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






36. A function whose graph is a straight line.






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






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






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






40. Same shape - but different size






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






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






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






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






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






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






47. Same shape - but different size






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.






49. 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






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