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 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






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






3. 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).






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






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






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






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






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






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






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






11. 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






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






13. 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






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






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






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






17. Same shape - but different size






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






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






20. Statement that two fractions or ratios are equal






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






22. 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.






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






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






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






26. Numeric value that does not change






27. Numeric value that does not change






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






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






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






31. 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)






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






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






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






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






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






37. (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.






38. A quantity that does not vary






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






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






41. 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
