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






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






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






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






5. 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






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






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






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






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






10. 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






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






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






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






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






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






16. (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.






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






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






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






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






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






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






23. 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






24. Statement that two fractions or ratios are equal






25. A function whose graph is a straight line.






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






27. 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.






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






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






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






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






32. A quantity that does not vary






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






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






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






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






37. 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






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






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






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






41. 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.






42. Same shape - but different size
