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






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






3. 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.






4. Same shape - but different size






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






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






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






8. 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






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






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






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






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






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






14. Statement that two fractions or ratios are equal






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






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






17. A quantity that does not vary






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






19. 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).






20. Statement that two fractions or ratios are equal






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






22. The reciprocal of a number.






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






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






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






26. Numeric value that does not change






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






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






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






30. 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






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






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






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






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






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






36. 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






37. 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






38. 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






39. A quantity that does not vary






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






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






42. The reciprocal of a number.






43. 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.






44. (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.






45. 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






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






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






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






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






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