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. 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






3. 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)






4. Statement that two fractions or ratios are equal






5. 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.






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






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






8. 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






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






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






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






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






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






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






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






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






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






18. 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)






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






20. 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






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






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






23. Statement that two fractions or ratios are equal






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






25. 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).






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






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






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






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






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






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






32. 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.






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






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






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






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






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






38. Same shape - but different size






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






40. 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.






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






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






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






44. Numeric value that does not change






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






46. A function whose graph is a straight line.






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






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






49. 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






50. A function whose graph is a straight line.
