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. Same shape - but different size






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






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






4. 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).






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






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






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






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






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






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






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






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






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






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






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






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






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






18. 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






19. 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






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






21. (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.






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






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






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






25. The reciprocal of a number.






26. Statement that two fractions or ratios are equal






27. The reciprocal of a number.






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






29. 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).






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






31. 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






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






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






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






35. 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.






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






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






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






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






40. 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






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






42. Numeric value that does not change






43. 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






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






45. A function whose graph is a straight line.






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






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






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






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






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