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 reciprocal of a number.






2. 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






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






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






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






6. The reciprocal of a number.






7. A function whose graph is a straight line.






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






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






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






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






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






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






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






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






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






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






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






19. 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).






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






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






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






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






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






25. Changing the order of the factors does not change the product; for example 10 x 9 = 9 x 10; a b = b a






26. 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.






27. The smallest number - other than zero - that is a multiple of two or more given numbers; The LCM of 10 and 18 is 90.






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






29. 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






30. 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).






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






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






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






34. 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)






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






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






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






38. 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






39. Specific form of representing ratios - examples - a:b or 2:3






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