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






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






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






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






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






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






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






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






9. (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.






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






11. Statement that two fractions or ratios are equal






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






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






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






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






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






17. Same shape - but different size






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






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. 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






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






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






23. 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






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






25. A quantity that does not vary






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






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






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






29. A function whose graph is a straight line.






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






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






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






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






34. All rational or irrational numbers; real numbers can be represented on the real number line






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






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






37. 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






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






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






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






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






42. 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.






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






44. All rational or irrational numbers; real numbers can be represented on the real number line
