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






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






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






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






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






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






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






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






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






10. Statement that two fractions or ratios are equal






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






12. Numeric value that does not change






13. 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






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






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






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






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






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






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. 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






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






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






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






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






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






26. 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)






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






28. 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






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






30. 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).






31. The reciprocal of a number.






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






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






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






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






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






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






38. A quantity that does not vary






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






40. Statement that two fractions or ratios are equal






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






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






43. 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.






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






45. 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.






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






47. 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






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






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






50. (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.
