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






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






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






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






5. Numeric value that does not change






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






7. Same shape - but different size






8. The reciprocal of a number.






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






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






11. Statement that two fractions or ratios are equal






12. 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






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






14. All rational or irrational numbers; real numbers can be represented on the real 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. Any of the natural numbers (positive or negative) or zero; any of the set of whole numbers and their opposites






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






18. A quantity that does not vary






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






20. The largest common factor of two or more given numbers; The GCF of 27 and 45 is 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. A quantity that does not vary






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






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






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






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






27. 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






28. 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).






29. (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.






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






31. 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






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






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






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






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






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






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






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






39. 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






40. A method of measurement that uses formulas - similar figures - and/or proportions.






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






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






43. The reciprocal of a number.






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






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






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






47. 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






48. 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
