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






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






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






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






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






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






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






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






11. (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.






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






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






15. 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).






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






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






18. Numeric value that does not change






19. 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)






20. A quantity that does not vary






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






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






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






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






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






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






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






28. The reciprocal of a number.






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






30. Same shape - but different size






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






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






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






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






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






36. 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).






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






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






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






40. 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






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






42. Statement that two fractions or ratios are equal






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






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






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






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






47. A quantity that does not vary






48. 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






49. 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
