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






2. 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.






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






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






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






6. Numeric value that does not change






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






8. 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






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






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






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






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






13. 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






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






15. Numeric value that does not change






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






17. 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)






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






19. 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






20. 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.






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






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






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






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






25. Same shape - but different size






26. 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






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






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






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






30. 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






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






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






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






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






36. A quantity that does not vary






37. 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






38. 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.






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






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






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






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






43. A function whose graph is a straight line.






44. 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).






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






46. (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.
