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






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






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






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






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






6. 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






7. 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






8. 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)






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






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






11. A quantity that does not vary






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






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






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






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






16. 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)






17. Same shape - but different size






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. Expressions that contain the same variables to the same power






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






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






22. (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.






23. Numeric value that does not change






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






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






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






27. 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






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






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






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






31. 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






32. 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






33. A function whose graph is a straight line.






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






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






36. The reciprocal of a number.






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






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






39. A function whose graph is a straight line.






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






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






42. 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.






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






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