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






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






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






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






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






6. Statement that two fractions or ratios are equal






7. A function whose graph is a straight line.






8. The reciprocal of a number.






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






10. 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






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






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






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






14. 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).






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






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. Numeric value that does not change






18. 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).






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






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






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






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






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






24. 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






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






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






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






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






29. 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






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






31. 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






32. Same shape - but different size






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






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






35. 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






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






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






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






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






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






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






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






43. 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






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






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






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






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