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. 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.






2. Numeric value that does not change






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






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






5. A quantity that does not vary






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






7. 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.






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






9. Numeric value that does not change






10. 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).






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






12. 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






13. 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






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






15. 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






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






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






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






20. 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.






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






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






23. Same shape - but different size






24. 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






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






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






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






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






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






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






31. (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.






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






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






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






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






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






37. 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
