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






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






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






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






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






6. Numeric value that does not change






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






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






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






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






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






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






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






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






15. Numeric value that does not change






16. 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






17. Same shape - but different size






18. 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)






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






20. 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






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






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






23. Statement that two fractions or ratios are equal






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






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






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






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






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






29. (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.






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






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






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






33. 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






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






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






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






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






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






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






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






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






42. 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)






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






44. 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






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






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






47. 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).






48. (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.






49. 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.
