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






3. Numeric value that does not change






4. 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






5. 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






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






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






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






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






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






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






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






13. Numeric value that does not change






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






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






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






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






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






20. Same shape - but different size






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






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






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






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






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






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






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






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






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






30. 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






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






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






33. 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)






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






35. 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).






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






37. A function whose graph is a straight line.






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






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






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






41. 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).






42. The reciprocal of a number.






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






44. 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)






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






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