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. (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.






2. 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.






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






4. 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






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






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






7. The reciprocal of a number.






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






9. 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.






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






11. 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






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






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






14. 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






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






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






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






18. Statement that two fractions or ratios are equal






19. 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






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






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






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






23. A function whose graph is a straight line.






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






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






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






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






28. The reciprocal of a number.






29. A function whose graph is a straight line.






30. Same shape - but different size






31. A quantity that does not vary






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






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






34. 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






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






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






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






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






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