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. 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).






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






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






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






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






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






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






8. 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






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






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






11. 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






12. 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).






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






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






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






16. 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






17. The reciprocal of a number.






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






19. 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)






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






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






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






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






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






25. 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)






26. Statement that two fractions or ratios are equal






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






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






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






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






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






32. Numeric value that does not change






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






34. Same shape - but different size






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






36. 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






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






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






39. 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.






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






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






42. 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






43. A quantity that does not vary






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






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