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 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.






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






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






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






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






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






7. A function whose graph is a straight line.






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






9. 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)






10. Numeric value that does not change






11. 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






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






13. 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






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






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






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






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






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






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






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






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






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






23. Numeric value that does not change






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






25. 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






26. 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






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






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






29. Same shape - but different size






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






31. 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






32. 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).






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






34. Statement that two fractions or ratios are equal






35. 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.






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






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






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






39. 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)






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






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






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






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






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