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






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. 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.






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






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






7. Same shape - but different size






8. Statement that two fractions or ratios are equal






9. 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






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






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






12. 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)






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






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






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






16. A quantity that does not vary






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






18. A function whose graph is a straight line.






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






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






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






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






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






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






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






26. 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).






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






28. (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.






29. 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






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






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






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






33. Numeric value that does not change






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






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






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






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






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






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






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






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






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 reciprocal of a number.






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






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






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






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






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
