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






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






3. Statement that two fractions or ratios are equal






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






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






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






7. 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






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






9. 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






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






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






12. Numeric value that does not change






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






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






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






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






17. (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.






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






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






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






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






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






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






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






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






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






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






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






30. 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






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






32. Same shape - but different size






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






34. 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.






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






36. The reciprocal of a number.






37. 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.






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






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






40. A function whose graph is a straight line.






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






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






43. 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






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






45. A quantity that does not vary






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






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






48. 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)






49. (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.
