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






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






3. 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






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






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






6. Same shape - but different size






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






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






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






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






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






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






13. 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






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






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






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






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






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






19. The reciprocal of a number.






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






21. Numeric value that does not change






22. 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






23. 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






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






25. 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.






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






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






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






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 quantity obtained by multiplication; the answer to a multiplication problem






32. 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






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






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






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






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






37. 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






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






39. (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.






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






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






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






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