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






2. 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






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






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






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






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






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






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






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






10. 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.






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






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






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






15. 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.






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






18. Statement that two fractions or ratios are equal






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






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






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






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






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






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






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






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






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






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






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






31. Same shape - but different size






32. (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.






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






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






35. 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






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






37. A quantity that does not vary






38. A function whose graph is a straight line.






39. 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






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






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






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






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






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






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






46. 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
